If I'm working with a RESTful backend API I use Backbone, if not I use Angular. Does anyone use a different criteria?

I can't say I understand why the criteria makes sense. Having used both I can say I don't use Backbone at all anymore. If I'm doing something where SPA makes sense and there will be complex logic on the client side I use Angular. If I just want to enhance what's already there I use jQuery in a components style that's very similar to Bootstrap.

I'll admit I don't really like Backbone much though.
