Tried it, went well for awhile, but when you get stuck it's tough to find support. Very small community. Probably 1000x less content/resources/references out there for it.
On the other hand NextJS/React have been both productive and intuitive. There are so many examples out there and people are constantly talking about the nuances of both here and on other sites.
It'd be great to see Next integrate something like TRPC/OpenAPI into it so calls to the backend could be statically typed. That would really polish up the end to end experience.
