There's a touch more than views to consider, e.g. do you have to build or want a native mobile app? Angular 2.0 will be under heavy development whereas I think React has matured to the point where a lot of effort is going into ease of use and performance [1]. I also found the React tool chain (using webpack/babel5) very slightly more sane than grunt/gulp once my project grew beyond "Hello TODO". But the JS tooling is absolutely crazy no matter what platform is decided.

I'm using redux for API calls - I like the "single store" approach despite drawbacks vs. flux (or multiple stores).
