I vote for it too. My favorite features are adding comments to highlights when reviewing a PDF and the tool to copy tables to clipboard that allows you to help it with the segmentation. I even got some of my colleagues that are on Windows into it, and I don't even use KDE Plasma as my DE.

I installed it a while ago based on recommendations I saw here. It works far better than Acrobat ever did. Deleting all of the Adobe files off of my computer felt great.
