Depends really. Both have their place. I've not used/touched angular and react I've only spent about a weekend on. However, I would say react is REALLY easy to pick up. I was/am impressed at how easy it is.
I could be biased though, I come from a heavy ES6 class structure background.
Why the only battle between Angular and Reactjs when we have the third player in market that is VueJS. In my opinion, Angular is quite matured framework and React JS exactly comes after it while Vue is still young in the market.
If anyone wants to know more about all three frameworks refer to this article ReactJS, AngularJS or VueJS .
