Typst is way simpler to learn, especially if you're used to markdown. You can first approach it as a markup language like markdown, but with some scripting.

Package management in LaTeX is infuriatingly bad, you can't even specify the version you want to use.

I can only speak for myself but I like Typst a lot more than LaTeX. Typst compiles instantly and the markup language is very reasonable. LaTeX by comparison is slow and arcane, with a macro language that is unlike anything else in common use today. It also has pretty awful defaults to be honest, especially if you're writing in a language that isn't English. There are a few things that Typst can't quite do, but that gap is shrinking as well.

Edit: This blog post has some examples and showcases a lot of the core functionality, including the scripting. Typst has a playground which you can use to get a feel for the basics (though installing it locally isn't a massive pain either, unlike LaTeX). Overleaf allows trying LaTeX in the browser for free as well, although only with an account (partly because LaTeX tooling is a pain and expensive in CPU resources).

As someone who used LaTeX for many years and then switched over to Typst, I see no reason to use LaTeX these days. Typst syntax is more readable and it is much nicer to write.

Especially if you’re coming from markdown, I think Typst is the better choice. Typst syntax is very similar to markdown for the simple things and more advanced things are like any super high level programming language.
