It depends. arXiv won't normally accept a LaTeX-generated PDF, but it will accept a PDF written in Word.

Particle physicists, cosmologists and astrophysicists almost exclusively use LaTeX (anybody using Word would get laughed at). In other fields of physics, Word is more common and also not everyone submits everything to the arXiv. It's an interesting cultural divide...

I wrote my thesis in latex and convert to html in 1995. It’s still online, 27 years later, and totally readable! Only a few external image links are broken.

I don’t particularly like latex though.

What do you mean? I predict the majority of PDFs on arxiv are generated from latex just based on the fields who mainly use it. In fact many papers contain the tex source files.

What I mean is, if you try to upload the PDF from LaTeX, it will complain and tell you to upload the sources (which it then compiles to a PDF).
