I agree with NP though. Heaven and Hell is an all time great, maybe the best of all the Sabbath albums, but the other two are not very good at all. Meanwhile, with the exception of Technical Ecstasy and Never Say Die, all Sabbath albums with Ozzy are classics and it's easily their best work. Ozzy just fit the band better. Even the reunion album, 13, is better than the reunion album they made with Dio (although I'm not crazy about either).
And even Ecstasy has You Won't Change Me, which is awesome and unironically one of my favourite songs by them, the Beatlesque It's Alright and Dirty Women, which was really enjoyable live.
But I agree the last two albums aren't really classics.
