I would say it depends on if your app is more consumery (react) or enterprisey (angular).<p>React will give you better performance and server side rendering.  It mixes the view in the javascript which can be a little off to some.<p>Angular will give you a larger framework with two way data binding and likely faster dev cycles.  There is a roadmap to 2, but until then no server side rendering and issues with performance if you aren’t careful.
