If you really want the *best* sounding drums, you need to get Drumkit From Hell Superior (DKFH). $300 for over 30gb of samples. They're in their raw format, so you need an external recording application like Cakewalk Sonar, Cubase, etc... to first route the drums (to a keyboard, virtual synth, or electronic drumkit like i do), and also apply mixing / mastering to get them to sound good. Here's an mp3 of the samples in action:
Sonor of Metal
You *could* hand plot all of that on the midi, althought it might be time consuming cause you have to plot every cymbal, tom, etc... If you got yourself a finger pad, or even an electronic kit like myself, its a lot easier.
I personally haven't messed around with those particular samples enough, haven't had enough time to learn how to mix/master, but I have recorded some stuff directly from my electronic drumkit samples, they don't sound too shabby either ;)
