The LaTeX Font Catalogue 5 years ago
I like the Computer Modern font when printed on paper.
On low DPI screens (e.g. 96 or even 144 DPI), Computer Modern feels too thin and spindly.
Recently, I came across the mlmodern (https://ctan.org/pkg/mlmodern?lang=en) font. It is a "heavier" version of Computer Modern and I use it for all my documents.
