I'd use myst for docs, it's simpler, lighter, and interlinks well.

Quarto is more for publications.

The main _technical_ difference between the two tools is the underlying approach to how we handle ASTs. MyST-MD leverages the unified-js tooling around AST handling, whereas Quarto uses Pandoc.

For UX, we think that MyST has a lot of nice bells and whistles, but we really need to author a blog post or documentation page to clarify the user-facing differences!

I was going to ask about comparison with quarto. I just managed to get a good quarto setup with typst to typeset documents and I'm curious about this alternative.

Quarto rendering is quite slow compared to Myst. It is more focused on R Markdown and Observable JS.
