> But even Atom stopped using React because it was so slow
That's a mischaracterization -- it was only slow for a very specific usecase -- rendering a source code text-view. (It's like using an optimized C plugin in your python project for that core part that needs the benefit of performance.)
React makes a LOT of sense for a JS framework, and it's not a surprise that it's among the most popular ones now. To simply call it unusable because ONE particular usecase did not suit it is doing it an injustice.
