What is Reddit's opinion of PDFedit?

From 3.5 billion Reddit comments

PDFedit is an abandoned low-level editor for PDF files.

Its functionality is unique in the FOSS world, and nowadays it's almost impossible to run due to it depending on Qt3 libraries, which are not packaged any more in distributions.

I tried it once but only use the basic features. Watermark only there if you advance features.

Other software you can try: pdfedit, inkscape (hard to use but it's good for single page pdf), and libreoffice.
