Well, I like a lot of them. A few still feel useless, like Hunter. I don't see any reason to be a Hunter over a Ranger or Druid, depending on which you liked. The Skald also seems oddly specific, but if I ever wanted to play a Viking...The Slayer still comes across as not quite powerful enough, but other than that isn't bad.
I really like the finalized versions of Shaman, Warpriest, Investigator, Bloodrager, and Brawler. They all have really sweet Archetypes, too. (I'm a big Archetype user).
The Arcanist and Swashbuckler definitely have their uses, but I prefer other classes to them. But that's mostly preference.
I honestly didn't see a ton of magic items I liked, but there are cool ones. There's one that allows a light weapon to pretty much function like a Hidden Blade from Assassin's Creed, except magically, so it's harder to notice. Also, a Staff that is basically a Shovel that casts Create Hole. XD
All in all, it's probably my favorite book since the Advanced Race Guide.
