I've been using Hugo as well. I used Pelican (Python port of Jekyll) for a long time, but Hugo is so much more performant and has a larger ecosystem at this point.
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! :-)
