I’d argue that Typst probably beats it on all levels. Have you ever seen a LaTeX document? (The question is rhetorical, of course you have) Just because it was the best thing before doesn’t mean it still is now. I’d say the only thing it still has going for it is momentum.
I looked at the Typst documentation and from what I could tell, it has 3 hard-coded "Modes" for 3 hard-coded kinds of syntax (normal, math, code). I couldn't find any way to add any custom syntax - is there a way to do this?
Tex/LaTeX are completely syntactically extensible. For example, a logician might want to use the software with any number of their notations, or a physicist drawing Feynmann diagrams, etc. I think at one point Lillypad used it for typesetting sheet music.
