Suggestions for best Bass Guitar samples ?

I have all you listed... While Trillian has a zillion options, huge library, and some very nice synth basses, I virtually always go with OT's Rick bass... sounds awesome, has a geddy lee sound that's just wicked (mostly use it in poly not mono) and the setups are truly awesome.
 
His Jaco is very nice also but man, I always end up the Rick...

OrangeTree's are probably the best sampled basses available at the moment. Ilya Efimov has some that are close, but not quite as flexible.
 
For synth basses, Trillian (or Omnisphere) are probably the most bang for your buck. There are also many dedicated synth VSTi's (like Massive, Zebra, Blue II, and so on) that all do synth bass of one kind or another.
 
The Scarbee stuff in Komplete is quite good, but there are only limited articulations in them which limits how expressive a performance you can get out of them, but for basic bass tracks, they are quite good.

I love OT's Rick and Cherry (and Upright Acoustic) Basses. I also use NI's Scarbee Pre and Jay basses quite often. Trillian sounds amazing, but the price has kept me from purchasing. 
You might want to consider Ample Sound's basses, while I don't own them, the demos are amazing sounding, and over the years they have improved the interface from the original products.

As you poll virtual instrument users, you'll find that they tend to have multiple bass sources/libraries, as borne out by the comments so far. The reason for this is that no single instrument does it all. It would help us if you cited some specific examples of the type of bass sounds and musical genres you'd like to emulate. 
 
For example, if you're after a classic pop or Motown sound, it's probably going to be a Fender Precision sample library. But if your style is more contemporary pop, you might do better with a soft synth than a sample library. My standard go-to bass is the OTS Rick, but that's because it suits my usual style. It would not be my first choice for folk, funk or jazz.

I was going to say this, but will quote it, so it's no missed.

Thanks so much for all the great inputs ! I really appreciate the wealth of experience that has responded.
 
Certainly, one thing stands out, many of you have acquired multiple bass sample options to cover the range of possibilities. Many of you specifically mention OTS Rick, which I think may well be the largest sample library in size and depth, and I'm certainly leaning towards that one for starters, since I think my flavour of down home Canadian folk pop-rock music style will use that type of sound mostly. (@ bitflipper . . . I've listened to some of your tunes, and think the bass in your recordings is amazing, so sounds like you use that OTS Rick a lot ? . . . though you obviously know a few things about putting it into the mix properly as well)
 
I think I have enough Synth bass sounds to last me a few dozen lifetimes, since I really only use them occasionally for retro type projects. It just takes so long to find the right one because there are too many.
 
I've played Bass guitar in many bands, for a lot of years, so I kind of know the sound I'm looking for, but I never considered myself a good bass player because I always had to cover lead vocals as well, so have spent most of my career thumping out root note bass basics. Now that I'm concentrating more on song composition and recording, a great sounding bass guitar sample will be really helpful, especially if I can get those articulations working easily.
I just haven't been able to determine which of the many bass guitar sample libraries has the best and most flexible articulation package ?
 
Others have mentioned . . ."Alembic, P-Bass", "Ilya Efimov", "Ample Sound's basses", "Stax" . . . I will be sure to search these out, thank you.
 
@ Sidroe . . . you really like "Scarbee Jay-Bass", and I'm wondering if you use it in any basic pop style music. I've  seen a few threads now that people are using this one a lot, but I always though it was for Jazz styles, and Slap bass type stuff. Whenever I try to use a Slap bass sample in my tunes, it just sounds too "uptown" and gets replaced very quickly by something more organic.
 
 

My most used seems to be the Scarbee PreBass, usually routed through Amplitube Fender, Ampeg or Orange Bass amp simulations.
 
 
I do like the playability of the Scarbee basses. Apparently Mr Scarbee was a bass player who got arthritis and made the libraries to be as playable as possible.
 
 
The Scarbee Rick is picked and the OT one is fingered. Both are very nice and compliment each other. Both have presets that use Kontakt's built in effects broadening the out of the box appeal. I also like OT Cherry and Jaco a lot. (it would be nice to see the old Jaco get a Evolution style revemp). Cherry was updated a while back and is a good all-rounder with fingered, picked and slap articulations, Its DI so will benefit from being put through an amp sim.
 
 
I only have one Ilya Evtimov bass, the fretless and I like it.
 
 
Finally a couple of off the wall suggestions
 
Ilya Eftimov's Contra Bass Balalaika and Bolder Sounds Guitarron bot make interesting acoustic bass instruments.
