Some PDF readers are better than others at displaying technically invalid PDFs. I've had some trouble viewing PDFs exported by LibreCAD in Evince, and a few other funnies that I can't remember now. Adobe Reader does seem a bit better at dealing with dodgy files, and of course it deals with the extended PDFs e.g. editable forms.Never had a problem with PDF forms using Okular.A reason to avoid Okular is its memory and disk size when used in an otherwise non-KDE environment. Far better than (e.g. virtualized) Windows with Adobe Reader, though :-)
However few people do completely without KDE or GTK programs these days, and disk & memory are cheap so that is really a non-issue. Plus KDE/Plasma is now divorced from its toolkit so you don't have to bring in all of the desktop to run an application.
25 years ago, creating PDFs was a hit or miss affair without Adobe tools but it's been a long time since I've seen a PDF that Okular couldn't handle. I do have Acrobat XI (from 2011?) running under Wine but it's been so long since I used it that I had to start it up to verify that it was still installed.
