Angular has some huge support and momentum behind it... there has also been a lot of job postings around it as well. That said, I couldn't get past some of my issues with it, and that server rendering (shared code) was not really a good option there... The issues with dependency injection is another issue, and testing pretty much requires a browser.

These are the reasons I'm using flux/react now. I'm really looking forward to following the development of Angular 2 now, and may just be my tool of choice for new development in a couple years.
