I have and use it alot. For straight Rock/Pop stuff, I think it have very useable sounds. I think it also has great beats built in. Lots of subtle hits and things I wouldn't think to put in manually.
Drums from hell is too much work, but sounds good
EZDrummer is much easier than DFH, but doesnt sound as good.
BFD sounds great, but (for me) is alot of work to get it to sound the way I want.
AD has less as far as sounds (about 5 kits and not much as far as hand percussion) but they sound great as is. For someone like me that wants to spend less time on engineering/mixing, and more time for writing/producing it works out for my songs.
and it sounds great.. IMO.
here is a little song I whipped together for a song my daughter (11) wrote with her friend. The drums to over all about thirty minutes. I used all built in beats from AD and just tweaked some of the fills.

Granted, its a little on the cheeze side, but the drums sounds great with little effort.
