Yeah, Page was great, rooted in the blues, but cutting through many styles, raising each to a whole new level. My favorites of his are:
Since I've Been Loving You
Rock and Roll
Stairway
Hangman
Immigrant Song
Re: Clapton. I have no problem with his homages to Robert Johnson and BB King. One should honor one's inspirational sources/mentors. (Though, I guess, as with anything, there can be excess). Also, I think the great bluesmen have on, balance, helped America's musical scene. I wish the brothers were listening to them rather than to the hip-hop people.
I like those mentioned thus far (at least those of them that I have heard--I confess I've been kind of out of loop--I don't know Vincent and Malmsteen, but I have heard Michael Schenker--Ja!)
For what its worth, here are my favorite guitarists, in no particular order.
Jimmy Page
Mick Taylor
Rory Gallagher
Duane Allman
Dickie Betts
Chuck Berry
Kim Simmonds
Jimi Hendrix
Keith Richards
Eddie Van Halen
Joe Walsh
Steve Howe
Eric Clapton
Peter Green
Stevie Ray Vaughan
Jimmy Vaughan
Johnny Winter
