Google Drive has better video than OneDrive

2018 - Google Drive added comments to Microsoft Office files. Your move, OneDrive !

Google Drive makes it easier for teams and agencies to use a mix of G Suite and Microsoft Office while working with their colleagues and customers. From now Google Drive users can easily comment on Office files, PDFs and images in the Drive preview pane without having to use (and potentially pay for) tools like Microsoft Office or Acrobat Reader — or having to convert them to Google Docs, Sheets or Slides files. That’s not quite the real-time commenting feature you get from G Suite or Office 365, but it’s still better than having to constantly convert documents back and forth between Office and G Suite. Thereby Google Drive is now more interoperable if compared vs OneDrive

2014 - Google Drive for desktop now allows to launch files in preferred applications to defeate OneDrive

Once installed, users will be able to right-click on applications stored in Google Drive and open them using a compatible application on their computer. Users must also have the latest version of the Drive app for Mac or PC installed and their files synced to the computer in order for the extension to work. Google says the new extension is rolling out over the next several days.
