I completely agree about Backbone. Backbone is a very simple tool. You can do a lot of damage if you're not yet a very good developer (or a very good Backbone developer), but if you care about your craft and the design of your application, it's fantastic. In fact, having the flexibility to make decisions about your application, forces you to make good design decisions. That is the mark of a great developer. With these other frameworks, which might be very large or very slow or very complicated, they enforce that design on you. For most projects, who cares? Use whatever is fun for you to use. Learn 'em all. But at a certain scale, it matters deeply what you hitch your wagon to.
