"Should I use Astro or Nextjs?" is a question I hear a lot...
At the end of the day, your project most likely won't be ruined by either framework, however, the correct decision for you can save you lots of time.
TLDR; I use Nextjs for anything requiring the support of a backend, and Astro for just about everything else.
