For my money, if you're looking for analog drum sounds, there's Drumkit from Hell Superior has no competition. If you're looking for speed with reasonable sounding results (and don't know much about drum processing), Linplug's RMIV is great. They don't add the flashing lights factor to your studio, but the proof, as they say, is in the pudding.
