Who is/was the best frontman in rock/metal history?

I have seen alot of concerts. I would havge to say Ozzy. NO ONE could get a crowd goin' like him. I saw him five times going back to 1982 and the last time in January and everytime he got that place rockin'. He didn't sound the best at times but he got everybody going. Steven Tyler was good, Bruce inson is very good.
