I disagree about Hendrix being overrated. I think he really revolutionized rock guitar, and his influence is still being felt.

I disagree about Page being able to play anything- don't get me wrong, I love Zep (an aside- my very first concert was Zep's first concert in Madison Sq. Garden before the release of the Stairway to Heaven album, and they did Stairway as an encore that blew the roof off. I was about 13, 7th row orchestra. Cost of ticket $7.50 if I remember correctly.)

I liked a lot of the groups Clapton played in, but he's on my overrated list. Great player, but overrated IMHO.

I'd put Mark Knopfler in the underrated list. And Gary Moore, who really can play just about anything. I understand he's considered the godfather of shred. I agree with the comment about Waters. As for Keith Richards, I think he's a GREAT rhythm guitarist.

This is the kind of debate that can go on forever.
