I'm wondering if y'all are doing edits to customize the kits, or mostly using presets. Having used Battery all these years, I'm quite pleased at how much you can alter the sounds in Addictive Drums...the main way I've taken advantage of this is to make acoustic sounds more "electronic," but I suspect I'll find some other uses as well.

AD is extremely flexible. We have an Alesis DM10X and by feeding X3d with MIDI we have adjusted the sound to be similar to acoustics. 
The only thing I can add as a potential draw back for some is that a fairly good latency for a guitar player of about 9ms is not good enough for percussion in real time. 
As an alternative to overcome this observation we can record MIDI in real time with sounds from the DM10X module (btw, not bad either) and then process it with AD. 
Kits and specific components have been fully modified. 

Depending on the song, I will tweak the kit to fit my vision if needed. For example, tweaking the pitch of the toms to spread out or pull in the pitch spacing, modify the kick envelope to adjust the ring of the kick drum, adjust the snare mics to get more or less sizzle, or abuse the heck out of it to get something completely insane.

I apply that to anything. If it has a knob, switch, lever, etc. I *will* twiddle it. Especially if its red in color. } B>

I been using AD for my Electronic tracks as of late and frankly it sounds awesome to my ears.. At first I wasn't a fan of AD, because Im a EDM guy but a few tweaks and filters I been getting a more polished sound to my tracks..

AD has a great deal of customization that complements X3 very nicely. I have taken to layering drums lately, and AD can more rapidly manipulate sounds than the program I use for layering (I use Geist via its "Spitter" plug-in for sampling). Although Geist is capable of these manipulations, its UI is a bit more clunky than AD for this purpose.

I use it mostly for acoustic kits... and I edit my kits (sometimes) quite a bit... sometimes I use the internal fx as other times I use ProChannel, occasionally using both as I always split all the outputs to separate Sonar Tracks...
 
It really is quite complete... One thing I'd like to see upgraded in it is how it deals with the cymbals... I've got a handle on it, but I can't say it's comfortable there... Don't get me wrong... The control set is there, but it would be nice if they (cymbals) were handled like the other pieces...
 
Sometimes I find I have to decrease the width of each crash so that I can control the location of the crash.... Feels a little awkward to me there, but it gets the job done...

I do edit the AD drums from their clean kits but to bring out the natural sound played.
I am mostly after a realistic sounding acoustic kit and AD is the best.
I do use the presets, more for what can be achieved.
It is incredible what can be done to a kit. 
 

Hard AD user here. I've always started from a preset but end up tweaking it, sometimes swapping the snare out, but usually just adjusting the sounds slightly.  

I'm using X2 but I've owned AD for almost 2 years. I do tend to use the dry sounds and process them myself, rather than the using the effects in AD. And I usually end up switching the snare or kick depending on the song I'm working on, or at least tweak the sound/mics. 

Less compression is an overall good idea for most of the presets, and brighting some stuff like hats or cymbals...anyway, at this point I always almost recognize when someone uses Addictive Drums,hehe, that does not means it sound bad!!..
