So, Ultimate Intrigue took a while for me to come to a complete opinion on.
The Vigilante class introduced in this book is, in my opinion, easily the best non-spellcasting class Paizo has ever created. It breaks up its social options and combat options in such a way that you have a great character able to participate in all areas of the game without having to choose whether you want to be competent in combat or in the myriad other facets of the game like exploration, social encounters, etc. It has deep and well-designed talents that allow you to pick any of a variety of different ways to participate in combat, with or without weapons, and numerous tools for allowing players to influence the story with safe houses, contacts, and more.
