If you like jQuery and DOM use Backbone. AngularJS does a lot more than Backbone and Angular forces you to do things its way, meaning to avoid doing DOM manipulation outside of the framework, which isn't necessarily bad but requires more of a commitment and learning.

AngularJS is great for simple apps but once I got beyond that I ended up fighting how to makes things work with the ng-* attributes often having to resort to $apply. Things that are simple with underscore templates and jQuery (the Backbone way) can become very frustrating in AngularJS.

AngularJS reminds me of ASP.NET controls with repeaters and coding through attributes. That works for a lot of people but I'm more comfortable with templates and jQuery.
