I moved from LaTeX to Groff years ago, mostly for the instant pdf rendering speed and much better templates (at the time). The math system also made more sense to me than LaTeX. Groff has an unusual syntax though and there are certain things that are still painful to do, but overall I still found it superior to LaTeX for those looking for another alternative. I may try Typst for a while and see how it compares, it looks promising. I’m particularly interested in how it does tables and diagrams. I did notice there doesn’t seem to be a table of contents generator but I might have just not been able to find it.

Yep, I’ve daily driven mine for a few years now, been perfect. No more wrist pain/numbness since. I’m also a vim guy and have had no issue with using the default key bindings.
