We recently faced a similar decision, and ultimately went with angular - the two-way binding sold it for me, plus the concept of pushing all DOM manipulation into directives (declared in the HTML), to get that out of the controllers. We've spent ~8 weeks using it: our codebase is smaller, easier to mantain/adapt, and better modularized -- we love angular. The docs are great, and the IRC community is there when you hit something quirky.
