Google Keep is a poor note manager, but a great app for content-capturing (text, audio, picture, drawing,..). Orgzly is basically the opposite, it's only text and great (for mobile devices) at handling this, but anything else is missing.

And Keep has a nearly perfect sync, but it's on Google for this. While with orgzly you are on your own, which can be annoying depending on how you sync.

Doesn't share your notes with Google for one. Uses a plain text file to store your notes. Org-mode itself is in a different league when it comes to note taking and organisation.

I find the ability work on emacs superior enough I'm moving my notes. Reorganizing is possible with orgzly. I don't use images anymore.
