John, easy. I'm not altogether certain any of the others would have been hugely successful without John. I guess Ringo was well employed in various marquee bands, and Paul would've gotten somewhere perhaps. But John was going to find Stardom, no matter who he associated with. I love George but there's no doubt IMO, he was "the lucky boy" who fell in with just the right people in the right circumstances. I am certain there's many would be musicians who persevered on the theory that "If George can do it, perhaps I can, too". It takes an extremely narcissistic person to image yourself as equal in stature to John. I didn't have to be told even once, I didn't have what he had. Maybe this is why as great as John is, people don't empathize and thus don't choose him as favorite. Please, let's don't get sidetracked into personal belief systems and things like that. It should be obvious, that's not what this thread is about or should be about.
