Quoted from Code_Blue:Ronnie James Dio studio albums ranking:
1. Black Sabbath - Heaven & Hell
2. Rainbow - Rising
3. Dio - Holy Diver
4. Rainbow - Long Live Rock n Roll
5. Black Sabbath - Mob Rules
6. Dio - Dream Evil
7. Dio - The Last in Line
8. Richie Blackmore's Rainbow
9. Black Sabbath - Dehumanizer
10. Dio - Strange Highways
11. Dio - Sacred Heart
12. Heaven & Hell - The Devil You Know
13. Dio - Magica
14. Dio - Master of the Moon

Hard to argue with that. On a personal level, I'd have Holy Diver and Last In Line up the top, followed by the Rainbow albums. But the Dio Sabbath albums are strong ... Soooo harddddd
