I rated it "excellent" based on player feedback. We've come from 5e and my players like the feats, a lot. Someone else in the thread said that they don't amount to much of anything, and that may be true, but players really, really, dig even the tiniest skill feat, let alone class feats that outright spells out new combat maneuvers. I guess if, balance wise, feats don't make that much of an impact, so much the better. In D&D everyone rolled variant human for the same set of feats everyone else took, so it's nice that Pathfinder throws so many at you as a player.
In contrast, it's all a pain to keep track of for a DM, especially when building NPCs. Players tend to rely on me to remember rules so there is a lot of page flipping. I've considered printing out "feat cards" for each class in order to try and avoid the constant book usage.
