I don't know. I'm not as familiar with Vue, but React's ecosystem is in such a good spot right now. Between things like RTKQ (or react-query), Material-UI, and react-hook-form, the abstractions over common web use-cases are just so terrific to work with nowadays.

And then just being the larger community, I just feel like all there's more examples in general for everything. Most things default to React as the guiding implementation.
