Ozzy osbourne (diary of a madman)or dio(holy diver)?

Great question! Two of my favorite rockers. I like Dio the best because he was and is by far a better singer than Ozzy and was and is the GREATEST metal singer of all time. Ozzy is by far the BEST frontman in metal history but the better of the two albums has to go to Ozzy. Holy Diver is very good but overall I don't see how any true rock/metal fan would pick different.
