Oh My. That is a dilly of a pickle. I am a die-hard fan of both, they belong in the "Great and Powerful Quad of Rock" consisting of The Beatles, The Who, Pink Floyd and Led Zeppelin I'd rather watch The Who perform, because although Zep is entertaining, I really get into Who performances (they do to, the only one who stays still is Entwistle). The band just had these really defined personalities, which made me connect with them. Not to mention Pete Townshend created Tommy and Quadrophenia, which are masterpieces. And Entwistle is an amazing bassist, and Keith Moon is the greatest drummer of all time. But on the other hand, Zeppelin has Robert Plant, who has a pure magentism and an amazing voice. I also like Zeppelin's songwriting which tends more towards the mystic. I'm also a fan of epic songs- which Zep does quite well. It really depends on my mood I guess. If I'm in the mood to be hyper and dancing and spaz out- it's the Who. If I'm in the mood to space out, it's generally Zeppelin. ~Layla P.S.- insult Pete Townshend and DIE
