We are derailing, you know.
I like 3.5 better partly because there's none of that "powers" nonsense (Heck, Tome of Battle was better. Powers sucked because everybody got them. Wizards didn't have spells, oh no, they had powers. Fighters got to hit people extra hard once a day for no real reason. It goes on and on,) but also because it has more room for variety. 4th acts like everybody's playing a dungeon-crawling sword & sorcery game where all the players are Stupid Good. They removed all the most interesting alignments. They didn't have rules for anything that broke from the norm--You have to be a murderhobo, because there's no house prices. You shouldn't be evil, because monsters are evil. You can't minmax at all beyond taking a race that boosts your primary stats. There's also the fact that the books act like you're using a published setting with premade adventure modules. There's also terrible crap that makes it feel like an MMO or a fantasy movie or something--you add your level to your AC (and, if you're unarmored and smart enough, your Intelligence, of all things) for some absurd reason. Gandalf here never gets hit, not because he's dextrous or anything, but because he's killed a lot of monsters and he's smart. The check penalty for wearing full plate armor is a whopping -2, compared with your friggin' +7 AC. Everybody knows that just swimming training is enough to not only entirely offset the weight of fifty pounds of metal strapped to you, but to still come out with a bonus while you, say, swim up a waterfall or something. Wizards get like 20-some odd hit points at first freaking level, while longswords still deal 1d8 damage, which isn't even a third of their HP. All the races in the handbook have +2 to two stats, no minuses. It's not a tactics simulator, because you need to try if you're going to die.
There's also crap like "DURR... CLANG!".
