I love also more Sabbath than Zeppelin even I really love also Zeppelin. And Sabotage is as great as SBS! Also I think there are some great songs in those two last Ozzy seventies albums, havenīt listened them a lot but I am going to listen them. Also even 13 is not as great as seventies albums, I think it is a lot better than any of non-Ozzy albums.
I really love also Cream, hard to say which is better, Cream or Sabbath.
I think Sonics were first punk band. And just my opinion, this is first punk song:
