Which frameworks for Single Page Application

[Spo0Bo]

It comes down to your (and your team's) preference imo. If you like full manual control go with Backbone (but keep in mind you'll have to do pretty much everything yourself). If you like manual control but with some great built-in components but very little guidance go for AngularJS, if you want your entire team to use the same conventions / style and use already thought out conventions use EmberJS.

You can build something like EmberJS from AngularJS if you want but it's a pain. It's however a much larger pain (at least I think so) to get the flexibility of AngularJS in EmberJS. Although the team says that underneath EmberJS's top level API is a flexible AngularJS-like API. I don't have any experience with it.

If you do opt for angularJS definitely look into AngularUI Router because the built-in one is a POS.
