Musically I love both their stuff with Sabbath, probably prefer Ozzy's solo stuff to Dio's though. Ozzy is just a clown and never wrote a note in his life though, and hasn't been able to sing for ten years. Now that he's suing Tony Iommi over ownership of the Black Sabbath name, all respect I had for the guy has completely disappeared. Not that there was much left after The Osbournes and the butter commercials...
