I'm sure you know I meant to type Plant the first time and not Page.
Plant sings like a girl while being a man, so yeah, he's got more range. lol Townshend was probably the second biggest influence on Jimi Hendrix's guitar playing after Eric Clapton. Doesn't make him better than Page, but I thought I would throw that out there.
Townshend I think knows how to build up what he's doing more. Page is great, but I'll take Townshend anyday. He's got rhythm playing that can take on leading playing like no one else.
