I spent about a day migrating my personal site from grav to hugo, and the main takeaway I got from that experience is that both of these "simple" static site generators are ridiculously over-engineered.

I could slap something together with a few lines of Make or Python that does exactly what I need, in an hour or two. I could even hook it up to AWS and have it update automatically.

Doing all of that is less time consuming and requires less effort than reading through the grav or hugo documentation, installing and setting everything up, and troubleshooting the inevitable problems.

The only issue I have is that doing front-end web development/design is not something I enjoy, so grav and hugo's existing library of themes is very convenient. Convenient enough to put up with the other annoyances.
