Disclaimer, I only read, and did not play the game.Having read and played the game, I'm gonna have to disagree hard here.
That being said, I generally don't like any kind of "class" based game, and IMHO, the playbooks are a lot like classes as they determine what moves you get.
The balancing mechanic was interesting and does suit the game world to some degree, but I still feel like the playbooks are a bit too constraining. Since this was my first PbtA game, I didn't know what to expect, but it just didn't really hook me in. YMMV of course
