I really am coming to love angular, but react is getting a lot of attention. Are they really opposing forces?

Is it a good idea to use react and angular together? Could I? **Should I?**

What are the pros and cons of mixing them? 

React is for UI, but angular can handle the controller and the view...but is react better at handling the view? Can we make a better app by relegating angular to the controller only? 

Any good resources for doing these things?

One thing I do like about angular that seems to be less true with react is that angular really allows you to have separation of concerns, whereas react starts to confuse this a little. It seems to be contrary to the angular-way, at least.
