I like the look of Zola, and I bookmarked it when I saw the README pick a bone with Hugo's templating engine. Take a look at the Hugo Discourse forum and I can't imagine less than 99% of the topics are about Go/Hugo templating issues. The Hugo docs basically say "we use Go's template engine, go learn that confusing shit and then we'll tell you 5 different deprecated ways to get today's date if you are enough of a masochist."
