ehh i dunno bout you guys but i dont use speed and technique as a way of finding out how good a guitarist is. personally, i think david gilmour takes the cake for me. i just love every single solo and riff i hear come from his guitar.

comfortably numb
another brick in the wall
money
time
have a cigar
wish you were here
shine on you crazy diamond

thats just to name a few...so hes my favorite. but other than him, i like angus young, slash, vai, SRV too...not a fan of satriani though
