In my case Tectonic (XeLaTeX with a few quirks, but error messages are actually readable) and Typst are both goto options when I want to write a document.

LaTeX is older and has currently more features. I would generally recommend it for writing serious articles and documents that need hyperref highlights for instance.

Typst still has a lot to catch up when you compare it to LaTeX, but I really like the overall document structure (except the table syntax, but I’ve seen worse) and design choices. In my opiniton, Typst has frendlier tools that just work (Neovim integration is amazing once you figure out the LSP and Tinymist).

Syntactically Typst allows faster typing, so you may use it to write notes directly during lectures.

Math parsing is a bit different, but also tends to be easier to write.

I also like that Typst works with different “elements” than LaTeX. It kinda fells more like HTML and CSS merged into one in terms of control and workflow.
