There were many times in the beginning of working with React when I checked out Vue because I was stuck. I was reading threads like this one where people were worshipping Vue and why it might be the better choice than React. People brought up many good points but forget one important decision factor most of the time:
While Vue has a big ecosystem, it's still a fraction of React's. And this is probably the most important thing about React: The ecosystem is so huge, that you have choice, strong competition between lib authors and at the end of the day often or usually superior products. You hate redux? Me too, but there are literally dozens of competitors or wrappers out there + React's own Context and Hooks which bring you quite far. You want a UI lib? There was guy on Reddit testing 40 UI kits for React. Animation? A dozen good ones plus one major one. E.g. I was looking for a page-transition lib for Vue for cross-fading page transitions (real cross-fading where pages blend into each other), I found nothing, just one which can do page-transitions but not real cross-fading (fade-out and then fade-in of the new page). Not that just that vast amount of libs makes life easier, there are so many people you can ask, React got the lingua franca of frontend.
Another thing I like is the actual (small) API of React. It's low-level and if you are stuck, you know quickly what the problem is. React shines also re maintainability , if I enter my biggest and quite complex React app after months I still know where to go and how things work.
Finally, the React team and how they manage issues is amazing. Their thoughts, their chosen architecture, their communication is far beyond many other maintainers on Github. You ask stupid questions in an issue, often Dan answers himself, always super friendly and helping out.
Once you passed the first weeks, I realized what smart architecture React has, that it never stands in my way. Just the fact that I am always and 100% in JS makes things so much easier.
