I know monotype is probably making their comment in jest... just the same, specifically ng2 vs react, I think that ng2 has a *lot* in the box, however I find that once you get past how to initially use react (specifically jsx, and a state management library like redux), there are very few gotchas, and some room to tweak. With angular 2, at least from my limited experience, there were a *lot* of wtf moments, and places where you can easily shoot yourself in the foot.
I admit, I'm biased, but there is support for that bias. Not to mention, I tend to solve most problems with a more functional mindset.
