Your opinion on React / React Native and Angular 2 / NativeScript?

Hello everybody

I'm web developer (student for now)and i've done some little project with angular 1 and react. But I want do bigger projects with this technology including mobile application.

So i think that i need to consider two different technologies :React/ReactNative or Angular2/NativeScript.

Do you have any advice or feedback about them ? If i spend lots of month for learning one of them framework, i hope using in my future job, which one can be more used in the few future years?

Thank's for your help !
