Mob Rules and Heaven and Hell... Headless Cross a very close 3rd.

Funnily, the Ozzy era stuff never resonated with me beyond the usual big tunes.

Skimming through this thread it seems I never actually answered the question. I enjoy a lot of the Ozzy stuff but all the 70s albums are littered with parts of songs that don't really appeal to me- the more upbeat hippy dippy bits. But when they hit they hit hard. I think though, on balance, and given the sheer amount of time spent with them over the past couple of years my picks would be Tyr and Headless Cross, in that order.
