Ozzy till the day that I die. He invented so much and has a great voice.

Looks like you just died on the forum.

You just died on the forum tonight!

Lol the 15 post countdown to self-promotion.

Black Sabbath with Ozzy in a landslide.

I grew up listening to Black Sabbath even though I grew up in the late 90's. I've listened to enough Sabbath and Ozzy to probably kill a normal human. I know I lost some brain cells along the way. Anyway for me this was an easy answer, Sabbath with Ozzy. I also like Dio, but for me he is a distant third in terms of not only vocal abilities but content. Sabbath had the whole package, dark vocal imagery, heavy riffs with great solos, and choruses that were incredible. I feel the Ozzy solo stuff also has much of this but with a slightly more polished feel. Although Diary of a Madman is incredible, I feel he lost something with the subsequent albums. No More Tears is excellent. Obviously music changed and production improved, but I think one would be hard pressed to find 3 better consecutive metal albums than Volume 4, Sabbath Bloody Sabbath, and Sabotage. I own all of them on vinyl and each record still holds up today. A lot of people rave about the early Sabbath stuff but for me the middle of the catalog is where the meat is, where the band is truly at their peak.

Dio era Sabbath by a hair over Ozzy era Sabbath. Ozzy grasping for air at the rear of the pack.

Come on, though. The best Ozzy Sabbath songs were still better than the best Dio Sabbath songs, weren't they? "Black Sabbath"? "Iron Man"? "Into the Void"? You know it's true.

I love all the Ozzy stuff as much or more then just about anyone. I just think Black Sabbath
with Dio Is a little more ballys and evil sounding. Heaven & Hell , Lady Evil, Falling Of The Edge of the World, Voodoo, I ... they have a lot of great songs In both line ups discographys.
I just prefer Dio.

Love 'em all, but Sabbath with Ozzy is my favorite.
