Adobe Acrobat DC is a full featured PDF editor. PDF Reader has a nice featureset for a PDF ... Reader, but is far from a complete PDF Editor.
PDF Reader is a PDF Reader, not a PDF Editor. It even says it in the name.

except editing files, it allows for everything you would like to do with a .pdf files. It is a buttons based app more like a GUI for a command line tool.

I love Sioyek because it has blazingly fast update time when a pdf modified. very suitable for latex with (n)vim/emacs user.
