Regarding Hugo, the Go template language is a little esoteric (or at least very unusual) at times. The final straw, though, was the lack of compatibility with the Tailwind JIT compiler. Apparently it's fixed now, but it took so long that I'd long since moved on.
Astro feels like a really good fit for static content sites. It's easy to understand, and generates very fast sites that don't rely on a tonne of pointless JavaScript (as was the case with both Gatsby and Next when I used them).
I am curious as to why you did Hugo thrice and why did you choose Astro in the end.
