I agree in terms of his emotional projection (which comes from a stoic stance on stage, weird juxtaposition...), however I think most of you are using the wrong word here when you say "technical". I believe David Gilmour IS a more technical player than Jimmy Page, that's why he has his sound. People always assume technical means "fast" or "able to play fast" but its not. Technical is the ability to utilize a certain aspect or all aspects of an instrument. In this case, he is more technical than Jimmy Page, where page is simply to me more fiery and able to let everything loose, make more mistakes, try things.
I love Jimmy Page, and I love most people you can name that play faster and more complicated things than David Gilmour, but i have NEVER EVER heard someone bring every noise a guitar can make out of one clean note, and that is why he is my favorite.
