* 53% of the respondents used React, and would do so again.
* 47% use "No framework", and would do so again.
(hmm. that doesn't leave much room, unless you can use more than one tool depending on the situation)
* 43% had "no interest" in Angular 2.
One other thing to consider, of the "had used X, would/would-not use again" responses: there is of course a lot of selection bias of whether or not to even try X in the first place.

My only experience with these so far is Angular 1. It's easy to get started with, but does get messy when you have a very large form (think "government work"). I don't have a "React" axe to grind, I'm just looking at the numbers.
However, by the time I have to haul in Typescript transpiling, much of the appeal of Angular 1 is lost :-(
(it feels like GWT, all over again, at least to some extent)
