I'd consider Ember to also be a top choice (if not the top choice) for teams who want to just go all-in on a framework and reap the productivity benefits. From all the frameworks I've tried, it's the one that's allowed me to focus the most amount of my time on actual product code, not plumbing.
Same here! Although it seems that Ember is getting little love from the HN crowd, we are very happy that we chose it for our company two years ago. I would encourage everyone who is looking be extremely productive and don't worry about plumbing too much to take a deeper look into it.
