Very nice comparison. Is it really time to move on from Backbone? I'm about to migrate a project to it because I believe in its potential to force me to write better js code in the long run. Should I not?
The question you should ask yourself is; "Is it right for you and your project?" It doesn't matter as far as your project if the community should be moving on as a whole or not. What matter's is if you, and/or your team, can effectively use the technology to reach your goals.
