Comparing React with Angular does not make too much sense, because Angular is a full blown JS framework (with router and many other addons). And React is only a UI component layer. But React + Cerebral is another story and it also is a full solution. Although faster, more composable and simpler than Angular.
Plus, you can't forget that React has nothing to do with DOM and browsers. The render engine is not a part of React. React can work with DOM as well as with SVG or native iOS and Android components allowing for building full native web apps.
