There is obviously terrible/no compatibility across Keynote and GDrive whereby GDrive doesn't work nicely with Keynotes auto-save function.
The biggest frustration we have though relates to all our MAC Keynote Presentation files. The main reason being is that we can work more efficiently across all the Google Doc formats in GDrive vs Dropbox. I have recently migrated our company (36 staff) off Dropbox and onto GDrive (1 x Shared Drive).
