I like it. I have been involved in software development for 20+ years - Perl, PHP, Java, Pyhon. And Nextjs and React gave me back the joy to develop web frontend again.
There are a lot of gotchas and considerations with Nextjs, but it is a framework and it is not unexpected that unless it is developed by yourself, frameworks require some getting used to.
There are some things that could be better, especially in non-Vercel-hosted scenarios, and if the backend for frontend part becomes too complicated, I would switch to Nest.js, but overall I am satisfied with Next.
