Amplitube versus Guitar Rig versus Scuffham versus Bias FX Pro...

i own them all and many more. imo s-gear2(scuffham) is over rated, i haven't fired it up since the 2.53 update maybe 18 months ago, it just doesn't sound or feel that good to me compared to others.
 
guitar rig, owned it since 3, own the latest, never use it, imo sounds like crap, cleans ok but overdriven, distortion, forget it, there are much better
 
amplitube, i own everything available for it, it's not bad, gets more use than the above.
 
bias fx pro, own it and bias amp pro, in my opinion a step above the rest
 
don't forget revalver 4, it is right up there, and with the release of the act stuff, especially act combo and act combo presets, oh what the hell even the act input modules, it has risen to the top for me (or equal top with bias stuff)
those act combo presets sound awesome. (you got to profile your guitar and a few other things, easy as, and results are awesome, imo of course)
 
for a long time i never touched revalver, it was all either bias fx pro or bias amp pro or sometimes th3 or amp 4. then the act combo thing came along and i gave it a whirl, and as they released more act presets (basically amps) i just began using revalver more and more, and not just the act combo side, even just the 'normal' stuff, now i pretty much use it exclusively, with the occasional switch, wish the stomps and fx racks were up there with bias fx pro though, but hey

what i have found in the past is that i may be noodling around with amplitube 3 or 4 or th2 or th3 or thermionik or whatever, and i'll just add drums and bass etc, every time when i switch the amp sim to bias amp or fx it's always just better, and i don't switch it back. i have at times done it in reverse, create the tracks with either bias amp or fx, then switch them out for one of the others and i immediately switch it back because it just doesn't have it. only revalver has ever withstood a switch.
 
in a similar vain as a test to myself, i'll sometimes just jam around with an amp sim, say one of the bias's, play for an hour or more so the sound is firmly in my head, then quickly switch to another amp sim with a similar sound dialed in, 99% of the time (100% really) the first thing i notice is a huge difference in sound quality for the worse, and i'll want to switch back immediately. again i can do it the other way and start of with another amp sim, get it firmly in my head, then quickly switch to one of the bias's, and it instantly sounds better. again revalver has been the only one to withstand the test, and usually it's with the act stuff loaded.
 
i started always using waves emo f2 i think its called, a basic hi/low pass plug, after bias, now i can't really use bias without it, it sounds so much better, don't really want to hear it without it, do it with any amp sim i use now and it always makes it much better. there's a few other things i do now days with amp sims waves ssl before, a send to a bus with valhalla room, which when i don't use them, well it's just not the same. can no longer use the standalone apps for any amp sim, i have to either fire up a daw or a vst host so i can set it up how i like it, it just sounds so much better. i would never use bias or any other amp sim without that hi/low pass
 
it's all a personal thing really, what sounds good to one doesn't to another, partly why i like to own everything so i can decide for myself. but they will all do the job, and there is things i like about them all, even gtr3 and amplion pro (well maybe not amplion pro )

Of the guitar sims I've tried, Amplitube 4 seems to sound the most real with the least effort to me. Now I'm not a guitar player, I use Orangetree stuff to feed in to it. I find that I can most reliably get the kind of guitar sound I want out of it compared to other things.
 
I don't have all the ones you've listed, I have Amplitube 4, Guitar Rig 5, TH3, and Waves GTR. Of them, only Amplitube and TH3 are useful to me. I don't find I can get good sounds out of the other ones. I find TH3 a pretty distant second to Amplitube in general.
 
In particular I find the Mesa/Boogie amps to be really good.

ReValver is the winner in all amp-sim tests for me. Besides having the most natural amp/cab sound and behaviour, it has a special setting for the pickup estimated output. It's not just an input level, which ReValver has too (with auto-adjust capability!). As we all know, hotter pickups drive amps/pedals harder. But when you plug your guitar/bass into you AI, and adjust the input signal to a certain level, the difference between hotter and lower output pickups becomes obsolete for all the other amp-sims, except ReValver. Besides this, you can tweak amp/pedal schematic, set amp-speaker interaction, use input/output ACT profiles... And now with the ACT combo you can clone any legendary guitar amp sound or use profiles created by other users. It works like the real thing, no wonder it sounds and feels like the real thing. 
 

I try to find answer on olpal`s question on youtube and found this

it may be usefull to someone.

IMO Amplitube has the best Fender sounds going. I'm not a fan of IKM but their Fender reverb amps are very authentic sounding. After that they all blurr together for me. S-Gear is very good so I don't see that buying another simm would actually do anything outstanding.

Bias FX Pro is supposed to have 32 amps and eleventy jillion pedals. That's the one I'm talking about. On sale for $159.00 now.

I'm with Grim.  Bias just stands out a tad above the others to me.  Plus, there are a zillion "user-made" amps online (though I think most are pretty poor). Grim is also right about Revalver, though most of the amps are either Peavey models or various hi-gain ones (Orange, Marshall etc).  If you're into clean you might struggle a bit with it. If you use an ipad I would recommend taking a look at "Flying Haggis" (it's a meager $7) and "Yonac".  Flying Haggis isn't modeled on any particular amp, but is the designers idea of an ideal clean amp.  I think it sounds great.  Yonac too is very good, but to me not quite as good as Bias.  One last plus for Bias is that it has the new "amp modeling" software included in the Pro package.  I, however, have no idea how that sounds since I just use the ipad version. 
 
Lastly, larry is right about the structuring of Bias' products.  It's totally bizarre!! 
 
Good luck to you!!

Didn't think much of Amplitube.  Tried Bias FX recently (demo/trial), didn't think much of that either.  GR is OK to pretty good, in particular I like all the fx and it has some fun high gain stuff.  For realism, I'd go with S-Gear every time; it's not a 'turn everything to 11' kind of plugin but it feels more real than any other plugin I've tried; it's not trying too hard to be 'dynamic' which is where I feel a lot of emulations go astray.  It's not trying to emulate or model anything else, it's its own thing.  Isn't it an ex-Marshall guy who produced it?  Anyway, I'd use GR, TH2|3 (plugins) or the GSP1101, THR10 (modelling h/w) if I wanted to go to 11 or beyond.
 
I've tried pretty much everything there is and will continue to do.  Some I really don't like at all (Amplifikation One, Thermionik), some is simply atrocious ('Hardcore' - b'wahahaahaa), much is rather 'meh' (e.g. Vandal), but there is some really good free stuff out there too (like Poulin's amps and cabs).
 
The point I'm slowly ambling towards is that pretty much all of it is free to try so do so and figure out what you like, what works best for you.

Just wanted to chime in here. I bought both Bias FX (not pro) and Bias Amp (not pro) last Christmas when they were on sale.  I have Line 6 Pod Farm 2.0 and have demoed both Amplitube and Revalver stuff.
 
I was disappointed a bit in the BIAS stuff in that I don't like the UI and the way you save presets. Since I don't have the pro versions most of the user contributed presets don't work for me and I haven't found a way to filter the ones that would work with my versions. I have been tempted to upgrade to pro but there is never a discount to upgrade it is always $100 no mater what the current sale price is for the Pro Version.
 
Also with BIAS I find that moving the microphone around doesn't change the sound as much as I would expect or have experienced with a real amp.
 
I like amplitube and have demoed several of the amps and pedals. I think overall I like this the best but I don't like thinking about always being tempted to buy a new package of amps.
 
I also demoed scuffman and thought it sounded great without much tweaking.
 
Of all of these I actually like my POD HD 500 through my real amps and cabs the best and I am not tempted to "re-amp" continually once recorded.
 
I have been looking at the Line 6 Helix and the Fractal AX8 as upgrade options, though, these are several times more expensive that a PC amp sim.

Anybody having any trouble running Bias Fx Pro in Win 10???

My ole pal. You got me thinking a little further than what I was already thinking when I posted. 
That is, I'm basically a guitarist and I noticed that I really don't pay too much attention to which sim is better or worse. Or amps, mics or whatever. I just grab something and go. Get the part down. In the end, it doesn't really matter. 
Just thinkin.

I agree after fiddlin too much on the "sound" side of Sims as i rolled along the learnin' curve for recording what I need to get a demo together.   I loved tweaking for awhile....I mainly stick with Amp4 now if Im not attempting to wrestle my Vox/Marsh combo via live mics ...which I love...but is hectic to keep it consistant when I move stuff about.  My recording space is much smaller that originally anticipated....but Im making do.
  I did consider the the Bias....i tried the demo and it was pretty good.....but not over the top for sounds I needed vs the Amp4.   Im sure your gonna be happy with it Olpal .....keep us apprised....I think you like fiddl'n....deff Bass'n around too huh  ;o)  .    I just recently realized the best recorded bass sound I ever got was my Dir Out from my Ashdown vs mic'n it live.....go figure....lol
 

I agree with Jim. I've gone back to using real amps lately, but my Axe-FX II was great and if I needed to record a simulated amp I think I'd pick up an AX8 for the purpose.
 
I recently did a demo project of the same song with couple of different amp sims vs. the real deal and posted it on my web site so I could share it with a buddy of mine who plays guitar and wanted to hear the difference.  If I still had the Axe-FX I would have done it with that as well.  It is hi-gain stuff, but I think the same applies to the clean and lo-gain sounds as well.  He went down the page; first was TSE X50, which wasn't too bad.  Then came Amplitube, which he liked better.  Finally, he got to the real amps, 5150 III first, which he preferred.  I added in another version with my new Boss Katana, and it was really close to the 5150, but he said he liked the 5150 just slightly more.  The modelers Jim talks about are darn close to the real thing, but the software sims are still lacking a bit to my ears.
