I started to play back in the 3.0 days (near to 2001); when 3.5 came out we switched to it without any problem except for the money "lost" in our 3.0 core books. I ceased to play in 2006 because most of the crew moved away from town.
I found a D&D 4E group in 2008 but I had the misfortune to play with a bad GM (IMHO), I played with him about six months and after that I was so tired that decide not to play more; my experiences with D&D 4E were not good and I started to accept things like "all classes feel the same" as arguments against D&D 4E. I've been playing pathfinder since 2010 and I have to say I really enjoy the game.
Since last year I started to play as well Mutants & Masterminds 3E (not sword & sorcery at all) and I can tell that all characters are almost the same if you remove the fluff (no classes here, just "concepts"), and the balance is as good as D&D 4E (if not even better) with the power level limits. The funny thing here is that things I believed were bad about D&D 4E are present in M&M and I don't feel them bad anymore, I really enjoy that game too. Now I would be glad to give D&D 4E another chance but right now I don't know about available groups to play in town.
So PF and D&D 4E are different games in many concepts, similar in others, but really none of them is better than the other, your perception just depend on things you like and people you play with.
