To help put this in perspective, how heavily did you use React before switching to Vue? How did you feel about it at the time, before you were aware of Vue?
Too much scrolling around, looking up the doc for every simple things, hard to integrate with legacy Python/Ruby/PHP frameworks, etc.
I went from jQuery then Angular 1, and was much less productive in React.
Also, introducing react to a new member in the team has always been dreadful.
All in all, I never benefited from the concurrency part. The performance yes, and the structure for the SPA. But the whole immutable constraint didn't pay off for me in the end, so I felt my stack was overkill.
