I actually write a good bit of React professionally. I'm familiar. I just have yet to see a very compelling case. And the excuse is almost always this nebulous "rich/complex interaction". And.... I just rarely see any good examples of this. The huge majority of apps (web or otherwise) are not video games. They're forms that submit stuff to a server and get a response. There's sometimes a dropdown here or there.... and that's it.
