I would suggest Typst nowadays. Much easier to get into imo. Unfortunately though it doesn't have backwards compatibility for LaTeXs math notation.

I wouldn’t, solely because it’s still in version 0.X - for any long-term, important project (e.g., PhD dissertation) I’d recommend LaTeX due to A) it’s mature and B) many universities provide LaTeX templates.
