I haven't tried Astro, but I moved my blog from Jekyll to Hugo.

I did it because I remember having issues with jekyll installation from time to time, like it suddenly broke out of nowhere, and trying to fix it became a pain.

Then I looked for alternatives and found Hugo, changed the template and installed in all my systems (Windows, Linux, macOS) and it has worked like a charm. Also, the speed boost was super noticeable, like, several times faster.

So if I were to choose again between Jekyll and Hugo, I'd go with Hugo.
