Whether or not typst is "superior" is largely debatable, but here are some reasons why I personally prefer Typst to LaTeX:

• leaner syntax
• less boilerplate
• (arguably) more intuitive syntax for math and formatting
• real-time preview thanks to incremental compilation
• automatic package management
• Ability to perform calculations/data processing inline inside your document (I know you can do this in LaTeX as well, but typst makes it easier)

However, as Andrew said, it is very much still in beta, so I don't think it can be a complete replacement for LaTeX. Basically, think of it as something in between LaTeX and Markdown. Less features, but easier to write.
