A better PDF annotator than Preview 9?

I am at the end of my rope with Preview 9. What I need is a pdf annotator that worked as perfectly as Preview 7.

I make several notes on pdf documents and need a quick, reliable, hassle-free program. Preview 7 was perfect. Each time I clicked on the page I could create a note.

With subsequent upgrades to Mac OS, Preview 7 became inoperable. I have tried to use Preview 9, but it's ridiculously and embarrassingly glitchy. Notes in the preview pane display ghost text from other notes. When I save a document via the "print" option and check the "Show Notes" box, some notes contain a "plus" sign at the bottom with the last line of text cut off.

And now Preview 9 is glitching the actual pdf -- sometimes pages start to strobe. I thought the app might be corrupt and tried to download a new file, but unfortunately Preview is embedded in Sierra.

I have tried testing a dozen other PDF readers but all fall short. For example, PDFelement takes three steps to create a note. Right-click to create note, double click on note icon, then click in note. I make hundreds of notes per document and this is just too many unnecessary steps. Plus, the note window popups tend to clog up a page and when I go back to edit the text in a certain note, I sometimes can't find it because the page is so crowded.

Can someone please recommend a pdf annotator that worked as effectively as Preview 7? I'm shocked Apple has ruined a good thing and even more shocked that no one has developed anything better.
