The main downside is that the Hugo documentation is sometimes terse and snarky.
Compared to really sluggish build times with Jekyll/Ruby it was incredible!
Some sites went from 10s of seconds to what felt like instant build!
However, with new versions of Ruby and M1 Macs, I dont notice build lag in Jekyll anymore!
And overall, I much preferred Jekyll and the way it structured sites, template and includes! :-)

* Eleventy
* Zola
Note that I excluded ones that output SPAs since I just want plain old hand-written HTML.
Jekyll’s biggest hurdle for me was installing a Ruby environment.
It can be seen here:
I'm doing a non trivial project with eleventy in my free time -- works well.
