I had to use Acrobat Reader on a Mac to work with a book publisher because the comments they were attaching to the manuscript didn't work the same on Apple Preview. PDFs don't behave exactly the same everywhere for things that goes beyond just reading documents. For example, I had a reply on the PDF that was visible on Preview but vanished when you tried to read on Acrobat Reader, that caused a lot of trouble with the publisher that claimed I didn't answer... YMMV with regarding to these features and them working across apps.
