Pelican started out strong with a good layout and structure out of the box.
However it used a lot of front-matter and if that metadata was wrong (or in my case duplicated due to my taste for cut and paste rather than remembering the mandatory fields) then the generator failed with a cryptic error message and the entire site failed to generate.
Ultimately it felt like a fussy version of Jekyll in Python
Jekyll is the daddy of static site generators due to its position as the default generator for Github Pages.
Jekyll does blogs and pages equally well, has a lot of good support and documentation.
It obviously requires Ruby and goodly number of gems and I think it isn't trivial to understand how to use metadata in templates but it is the yardstick for home to judge this sector.
Pelican seems pretty nice for blogs but for categorised pages of information Jekyll still seems to be best.
Wintersmith is entirely Javascript-based (which means you don't need to worry about Ruby and installing Gems) and by default has a beautiful template.
It does seem very post-based despite its claims to be flexible.
I haven't tried to use its integrations to build a SPA yet though, something that the information site mentions.
