This icecream is a terrible vanilla!
Umm... it's strawberry./snip
The reason in this case is because a lot of folks didn't find 3.X wizards over powering, while some 4e players cannot wrap their minds around the fact that it is either subjective or circumstantial.
It comes down to style of play.

The Auld Grump
Again, I'm not terribly familiar with the Pathfinder rules, other than what I've gleaned here on the boards, but, didn't Paizo jack fighters and other classes way up in power in order to bring them in line with casters?
Wasn't that one of the stated goals of the system?
If it wasn't, why did fighters and others get so much of a power bump if not in recognition of this problem?
While there are numerous ways of dealing with the caster/non caster issue, the fact that both 4e and Pathfinder did so kinda means to me that there was, in fact, some recognized problem.
Claiming that there was no problem, when the system you play addresses the problem directly seems a bit odd.
