In a way this is a difficult question.
Billy Cobham completely and totally wipes the floor of Peart, Moon, etc.. with the speed, tempo, timing and power of his playing. He would no doubt be an incredible addition to any rock band. Much of the material that I've heard of his (both his solo work and his playing w/ the Mahavishnu Orchestra) certainly 'rocks' and would have no problem finding the place in the rotation for anyone who really enjoys rock instrumentals. Problem is is that (AFAIK - unless he's done session work for someone that I'm not aware of) you won't find his work in the Rock section of your local record shop. It's filed under Jazz.
For rock band drummers, the drummer I find that I enjoy the most is Phil Collins.... but what impresses me the most is his Brand X playing (and that's a jazz fusion outfit). His best playing outside of that (like Los Endos) is extremely influenced by both his jazz fusion work & his influences in that area. A huge percentage of the top drummers are in fact influenced by jazz drumming.
Now one drummer who doesn't appear (at least to me) to have any 'jazz' influence that deserves kudos is in fact Keith Moon (his influence I believe came from surf music). His lightning fast 'fills' adds so much to the Who. But I don't know how adaptable he was.
Another who deserves kudos is in fact good ol' Ringo. I think he hated to solo (at least on record). But what he did served the song. In the end, that's what you are supposed to do.
I like Peart. His playing on 'Tom Sawyer' stands out to me far more than any of his solos. But a person on a newsgroup a few years ago (someone who's opinion I respect since he can analyze things far better than I can and can play several instruments while I play...none) pointed out that before Rush started supplementing what the 'three' played actually live on stage with prerecorded material (triggered by them onstage when those parts come in, but prerecorded nonetheless - they opted for that approach rather than play with those sounds 'missing' or to get extra musicians not in the band to play them live for the tour), he couldn't keep time if his life depended on it in a live setting. But in his favor since he isn't just the band drummer but the main lyricist (and who often has a point of view he want's to get across), he has an interest in serving the song so he's pretty good in how he uses his drumming talents in the song creation process and not to just show off.
