According to my opinion music and drumming is subjective, and everyone will have their own idea of who the best drummers are.

My FAVORITES are these, at least right now. Tomorrow may be different.

Vinnie Colaiuta ( He can play anything out there.)
Gregg Bissonette
Phil Ehart (Kansas)
Mike Portnoy
Will Kennedy (Yellowjackets)

I have been a drummer since 1967.

I only know Portnoy... is that Matt Bissonette's brother? Anywho,

Mike Portnoy
Virgil Donati
Brian 'Brain' Mantia
Tim Alexander
Danny Carey
that Mastodon drummer
Carter Beauford
Ozric Tentacles drummer
Neil Peart
Mitch Mitchell

Tim Alexander
Micheal Bland
Vinnie Appice
Fred LeBlanc (drummer/singer for Cowboy Mouth. Look 'em up on you tube).

he is such a douchebag. yeah hes good but there are definitely better I can think of like Zach Hill or Greg Saunier.

All these prog drummers are lame. I have respect for them and everything but they really don't compare to some of the drummers today.

Carmine Appice
Carter Beauford
John Bonham
Bill Bruford
Neil Pert
Mel Taylor
Charlie Watts

I love the drums on the old Black Sabbath stuff. Especially War Pigs.

I'll go with:

Terry Bozzio
Mike Portnoy
Charlie Watts
Jon Fishman
Stewart Copeland
Bill Kreutzmann

I'm surprised you mentioned Charlie Watts, because he gets entirely overlooked.

I love some Charlie Watts. Phenomenal drummer, and my favorite member of The Rolling Stones.
