Pro Even works without ROOT
Greenify even offers battery savings to non ROOT devices, though it may be limited compared to what can be done with ROOT and Xposed.
Pro Hibernates, instead of freezing apps
Greenify's mane function is to hibernate any installed apps. This allows users to to quell overly active apps that are draining their battery without having to delete them. This can be done with or without ROOT.
Cons
Con Finding certain files, like images, can get difficult if they don't have a unique name
Files tucked away in the vault don't show a preview of any kind. If the file can't be identified by the filename, it has to be unhidden to see its contents.
Con Greenifying without ROOT has to be done manually each time
When using Greenify without ROOT access to hibernate apps, it has to be done manually each time. There is a widget and shortcut that users can set to their home screen to make this action a bit easier though.
