As someone who is still relatively new to front-end development, I found a lot of comparisons to be just as confusing as the frameworks. Finally, after reading all the reviews I settled on AngularJs for one major reason....
...it was built by Google.
Perhaps not the best reason, but sometimes you've just got to back a horse.
As a side note, I have just started doing an AngularJS with Pete and Jayrd at Coder Factory. Highly recommended, if you want to learn to code.
