I agree with Naf, Ozzy isn't what he used to be, Bruce is still on to of his game! I absolutely dig Rob & Dio completely, but since I can only vote for one, it's BRUCE all the way! It was easy to put Ozzy aside, next was Rob because I like him but he's never been "Whoa" to me (except the "Halford"albums are phenomenal!).. Dio, that man has one incredible voice and singing ability, and so does Bruce... If It came down to it, I think Dio could beat the ass of anyone else but Bruce.
