I've got DrumTrax . . . They're good for MIDI and at least come with 1 , 2, & 4 track samples for more realism potential. What I mean is; when the Kick, Snare, cymbals, & Toms are on separate tracks, you can dupe, adjust,pan, & enhance tracks independantly for more realism. I like to complete the MIDI tracks - convert to independant audio tracks - then process- ie compression , EQ, etc, even add live tambourine, woodblocks, cowbells, crashes . . . it takes time, but the results are worth it and I don't have the space or budget for a real Drum set.
