Id give it to Floyd...as much as I love Zep.

Floyd were definately more creative and I rate Dave Gilmour just as highly as Page- If for no other reason than Gilmour can still do it- Page has difficulty playing his stuff these days (and has been for a long while), especially lead riffs.

I also have it on reasonable authority that there may be a Zep reformation in the works (with Jason Bonham on drums). I was initially skeptical- was thinking it would most likely just be Page & Plant but no- it is supposed to be the Zep- whey hey!
