that was 10 years ago. Isnt there something better now ?

It might even be negative is my guess. Lot of automated tooling is used. And I believe those have considered popular word processors so at least Word and Google docs. On other hand if your own toolchain outputs something weird it might not get captured in same way.

My rule is:

If it has a lot of equations, use LaTeX

If it has a lot of text, use Word/Docs/Whatever

The advantage of LaTeX is that you can use "Macros" to ensure a consistent style. You can also do that with "Styles" in Word, but nobody uses them. (I'm not sure if Docs support styles.)
