Personally, I don't think Pathfinder goes far enough to balance casters and non-casters. Fighters get a few extras thrown their way, but comparing their DR 10/- to something like the benefits a high level shapechanging spell will give you is still a rather bad joke.
Wizards get some more perks in Pathfinder than in 3.5. I think there's a certain level of admiration for the Vancian system at the core of Pathfinder. And if your disatisfied with spell casters in 3.5/Pathfinder then 4e is more your cup to tea.
One of the big changes, I've noticed is animal companions for druids. I played a lot of Living Greyhawk 3.5 where the druids animal companion could kick but esp at higher levels. No so much in Pathfinder. You don't have gargantuan T-rex's running around anymore. Animal companions have been cut down in power.
