Can I say neither? I never got into either band when I was younger and they were at their peak...It wasn't until I was older and wiser that I went back and explored a whole bunch of music that I had overlooked as a youth. I can say I've at least seen Sabbath live, on "The End" tour last year...they sounded really good! But seeing as this is a poll and we are being forced to pick one over the other, I'm gonna go with Zep. Overall more appealing to my palate.
