I could not agree more. Listen to Gilmour on Shine on You Crazy Diamond. He's on the Strat and the lap steel and he's genius on both. Just amazing. Jack White and his (i think) strident vocals and sloppy guitar work don't come close to Gilmour - not even in the same city, let alone ballpark.
Jack White, what I've heard of him, sounds like a cheap imitation of Thurston Moore and Sonic Youth, which I never thought much of either. I hate that "art" rock sound...the whole "if I sound bad and dissonant enough, maybe everyone will think I'm doing it on purpose and think I'm brilliant". You find that a lot in post-MTV guitarists, those who saw videos first, then decided they wanted to play guitar.
