Bigger jerk, Gilmour or Waters?
I'd have to say Gilmour. True, Waters has always been outspoken and dictatorial, but somebody had to have the personality to take over the band. With Waters in charge they produced some of the greatest rock albums in history. I didn't enjoy any of the Gilmour led Pink Floyd albums, they were severely watered(haha) down.
I think deep down what Gilmour was really pissed off about was writing credits, he wanted to grab more money with both hands and make a stash. Greedy Bastard that Gilmour is.
