Cameron - Awesome.
Chamberlin - Makes me cringe half the time. The man refuses to just play beats.
Peart - a one note joke that was the centerpiece of a horrific band.
This is not to say that Chamberlin is bad, because he obviously isn't. His playing on SD and MCIS is pretty rad, esp. Jellybelly, Rock, and TtEoR, but on the Zwan album, he is awful.
Pearl Jam had a really good string of drummers - Jack Irons and Dave A were both fantastic, though polar opposites in terms of style.
And the guy from The Flaming Lips... he's all bass drum. Its nothing short of great.
