There are a bunch of them out there, and it's really hard to single out only one so I'm gonna name a few that I think are good.... Nick Barker (Uncle Fester himself), Hellhammer (holly fucking shit), Pete Hammoura, Mike Portnoy, Trym, etc...Paul Mazurkiewicz is a good drummer, but I think he should play in a band that's a bit more serious than Canibal Corpse.
dolphz - I heard Vader a few days ago and they are quite good. Your're right their drummer is a maniac.
.....and Nico McBrian of Iron Maiden of course.
