My number one is definitely Danny Carrey from Tool. I love Dave Weckl from Chic Corea Electric Band and Brad Wilk from Rage Against The Machine and Audioslave as well. My favourite jazz drummer is Buddy Rich.
I like a lot of the other technical monsters out there like Lang, Peart, Bozzio, Weckl, Minneman, etc.
Bonzo and Bruford certainly are an influence.
Benny Greb is a recent discovery for me too; he's pretty awesome
I would have to say my fav drummer switches alot jst by wat modd i am in but currently its Danny Carey! (duh)!!! lol but 2nd of all it would be Abe cunningham of deftones 3rd Tim alexander of primus who jst left the band recently 4th it would have to be Martin lopez of opeth and finally 5th but not last Steve Gadd i have even seen him live he's a amazing guy , and a all around great!
