Not sure how you'd come to the conclusion that "large part of the JS community has started to settle on React", other than confirmation bias of reading Hacker News and a lot of recent discussion about what the new hotness is.

I'd rather use a gauge of number of people showing up at Meetups, number of jobs in job searches, etc.

At my current guess is that the AngularJS camp is at least 4x the size of the React, and even that number is likely low since Angular is a lot more stabilized in all the enterprise environments.
