I built a web-app for my previous startup in Backbone, after a year and half working with it, (1) I got frustrated with the amount of files I had to create, (2) its performance, and (3) the difficulty to write pure tests, (3) no concreate convention. EmberJs doesn't relieve me of any of these problems other than convention, but I'm currently working on contract work that has me using EmberJS I didn't like Angular for many reasons, but they promised to solve my big 4 problems. What I didn't like at first about Angular. Cocumentation is written from what I'd expect from a computer science major, I had to litter my dom with tons of tags and I had to overcome the idea of their syntax as ugly. But it did everything I needed. I reduce my javascript by 70%. I got ride of most of my other 3rd part libraries. Performance was awesome. I didn't need to figure out how to compile all my templates into one js file. It made testing dead easy since all I was left was logical javascript.
