I've been doing my work with Ember (co-founder/only developer) since version 2.0 (currently 2.15), and I really like their approach to things.

I feel I'm very productive with Ember (not being a JS guru). The whole ember-cli plus addons makes it a breeze to start a new application/enhance an existing one.

Also, the work being put on Glimmer making Ember faster and pretty much the only thing I had to do was to update my package.json and install the new version (granted If I did that the minute it was released some addons do break, but if you wait a little/contribute to fix those issues... it was great).
