Interesting you mentioned Ember, which I'm a fan of as well as Angular, though I've been using Angular almost exclusively for severa weeks. One key difference for Angular is that your markup ends up pretty much exactly how you want it. Ember had <script> tags littering my DOM for binding purposes, which made progressively enhancing forms (and leaving the standard submit event) require manual cleanup prior to letting the page change. To Ember's credit, it is refreshingly opinionated, and solves the very difficult problem of handling complex states and transitions to deep portions of the app.
