Edge (David Evans) is a decent choice too. He's up there. Maybe not the best of all time, but certainly a true innovator. I don't think I've ever heard anyone else with so much of an ability to track timing. He revolutionized the use of delay and turned it into a beautiful augmentation for the sound of the instrument. Very difficult to play well/effectively with lots of delay effects (try it sometime!) His technical ability isn't too bad either.
