You're a full time Angular developer, you obviously know more about Angular then you do React. So why would you switch to using React? At the end of the day both can do the job just as well.
Why does anyone ever do something new? Curiosity? Maybe I just feel like there can be something gained by learning a slightly different way of doing the same thing?
You need to keep yourself marketable. There are plenty of interviewers who expect most good JS devs to have React knowledge. It's the hot framework right now.
Angular 2.0 takes a lot of the good stuff from React so I think it's much more pragmatic for the average Angular dev to wait for that and learn that first. If Angular 2.0 fizzles, then learn React.
