Start learning angular2 or react?

This year I learned and developed with Angularjs (yep, better late than never) and I like very much the concept of MVC on client side. But recently Angular2 is came out and it seems to be very (very very) different from Angularjs. Here are some significant changes: - Components oriented (like react) - Use TypeScript instead javascript

Now I'm facing the dilemma: start learning Angular2 or React?

Some questions that can help the response: What is the learning curve of each one? What will be probably the trend? There other lib better than these ones?

There are some interesting articles but the doubt remain:
