Earlier quoted context omitted.
LaTeX typesetting is a solved problem. Memoir or Classic Thesis, paired with microtype, provide outstanding results and you need to spend zero time on tweaking stuff. Typst is interesting, but it doesn't yet support all microtypography features provided by microtype. IMHO, those make a big difference.
What in microtype makes "a big difference"? I don't recall using it (my LaTeX years are long behind me), but all of the examples on https://www.khirevich.com/latex/microtype/ seem incredibly minor. I don't think I'd notice any of them as the reader.
It is what sets professional typography apart. Only Adobe InDesign provides a comparable implementation, tweaking all those details.
See https://en.wikipedia.org/wiki/Hz-program for a better explanation and an example.
IMHO, the difference is obvious and not minor. Without microtypography texts look ugly: https://upload.wikimedia.org/wikipedia/commons/0/03/Hz_Progr...
