I have played a little Pathfinder of both editions, and they feel like nothing so much as someone's 3.5 house rules trying to fix the things that personally annoyed them.

I admit I tend to ignore them though. Some of the devs were kinda shitty during the public playtest phase of Pathfinder 1 towards playtesters who were actually trying to do systemic testing (rather than, I guess, they just wanted groups to play it as a vibe check). In the grand scheme of things it wasn't that big a deal, and probably doesn't justify still being vaguely cranky about. But it soured me on the project and there are a lot of other games I can play instead.
