I've been looking at this from a slightly different level. React may be the best choice for a UX on the web but I think it's still far worse than any native app. It's one of the reasons I get so disappointed after hearing about something cool and new and then finding out it's an Electron app.

I'm stuck on this idea that the best UX is a native app for performance reasons (responsiveness, memory, CPU, battery), aesthetic reasons (assuming your like your native platform) and longevity. On my desktop I often run applications that are a decade or more old. How many web apps rolling out today can sit untouched for the next decade and continue to do useful work?
