EZDrummer, and the other examples are a different beast. Those are sample based drum plugins. They are made to sound like real acoustic drums. They are great and wonderful.

This is a pastern based drum machine for non-acoustic sounding drums (Usually). So you are comparing two different tools.

EZDrummer actually is a pattern+sample based drum machine like Hydrogen, while Studio Drummer uses pre-recorded audio patterns which could be wonderful to listen to but are very limiting in my opinion, even if played by world class drummers.

The only difference is the set of samples used. Hydrogens sample section, like soft-ROMplers such as NI Battery, has a multi layering method of arranging samples for each instruments according to the played velocity. Actually it offers even more layers than Battery so with the right set of samples it could even sound more realistic.

The only problem is the lack of free real sounding acoustic drum samples as most people don't want to use them in favor of distorted sounds with ton of effects. This is so wrong; a decent sound engineer can get the "industrial" sound out of a jazz acoustic set, but no mixing console god in the world can do the other way around. Never ever ever ever sample drums with effects, always record the samples dry and add effects afterwards when needed.
