As with most 'Top/Best' lists, I would find it impossible to come up with a definitive choice, as there are so many great drummers (in the 'world of rock', let alone other genres!); however, three that spring to mind:
Neil Peart
Mike Portnoy
Barriemore Barlow
Stewart Copeland (Police)
Manu Katché (Various, but famously on Peter Gabriel tours)
Max Weinberg (E Street Band)
Uggh ... showing my age there
