Are they the platforms of choice for everything else? I tried to find me a PDF editor for linux, again, happy to hand over money, I got a trial for a program that was god awful and did not count as it could not properly deciper the PDF and allow me to edit text with every word being split into multiple text boxes.... On windows i have many options. All other programs claiming to be PDF editors were all lying as all they banged on about was adding notes to a PDF not editing the original text.
I use Inkscape for this. It only does one page at a time, though. Note that you do need to obtain the font used in the PDF, to be able to edit the text and not have it look all wonky; the default font name matching is less than optimal. I typically first split the PDF into separate pages (
pdfseparate source.pdf page-%05d.pdf) or page groups (isolating the to-be-edited pages), optionally convert the PDF to PostScript (since there are more editing options for PostScript than PDF), edit the pages in various tools including Inkscape, then combine the pages into a new PDF.
I used to have a very capable cow-orker who demanded self-contained applications suites and editors, just like they were used to having in Windows. I tried to help them see that instead of looking for a
specific type of tool, they should concentrate on
how to solve the underlying problem. They refused (by saying they weren't interested in that, and just wanted to solve the problem at hand without wasting time), and kept calling Linux "open sores crap", because it wasn't sufficiently Windows-like.
As long as you use Linux as if it was a no-cost version of Windows, you will be unhappy.
