Ask HN: what do you think of this 3 MVC JS frameworks benchmark?

Hi there, I have various JS scripts in my apps for different uses and purposes, and I need some refacto here: some small features heres, some one page full JS version for mobile app...

We currently are on Backbone.js and liking it a lot. I'm curious about Ember.js and Angular.js maybe for some heavy refactoring in a one-js app. Here is a small bench that I made out of these 3 frameworks / libraries.
