PostScript is a full programming language, so it is much harder to provide
security for PostScript: https://www.theregister.com/2017/01/31/postscript_bug/,
PDF can embed scripts, but those are more of an issue for viewers
than low-end printers. 

PDF has better support for the Unicode fonts commonly used for
non-Western language documents (for me, using English, but with
colleagues from all over, names of people and places are
problematic for PostScript producing applications).
