I think the new features in EZ Drummer 2 are pretty cool
Especially for the Songwriter who needs a relatively quick/easy solution to provide solid drum tracks (who may not have the time/skills to break out drum pads).
I don't think the sound is bad.
I liked the toms on the DW kit.
I'm not crazy about the DW Edge snare samples. I have one of those... and (IMO) it sounds much better tuned a little higher and damped just a tad (though not completely "dry").
Not a fan of the Kick samples. Too much click and not enough fundamental. Felt this way about EZD1
The cymbals sound pretty good. I like the cymbals in BFD3 a little better (but that's to be expected given the size/extent).
Having started musical life as a drummer (what seems like a century ago)... and having spent a lot of time recording acoustic drums, I'm very particular about what I want to hear. The tendency of late (to enhance the sense of reality) is to record "wide open" (IMO) overly resonant kicks and snares. Sort of the opposite of the 70s super dry "cardboard" sound. Some folks love that natural open drum sound.
I like drums just a little more controlled sounding (at the source).
As great as BFD3 is, I'm not crazy about any of the stock snare samples.
One thing I really like about BFD3 is the ability to "damp" the various drum samples.
The snares in BFD3 ring a lot. I don't like a totally dry/dead snare sound, but a little crescent of felt is a wonderful thing on snare drum.

Lets the snare breath... but eliminates that nasty ring/ping that you'd otherwise have to tame at mix.
The above said, the purpose of EZD2 really isn't to provide the ultimate drum kit samples.
It's to provide a good sounding set of samples in a format that makes it easy to create decent drum tracks.
In that regard, EZD2 is certainly a success.
