I've run no tests, but OneDrive has had it's ups and downs with me. I've had MS reset OneDrive several times (requiring hours of time in multiple chat sessions) because some things showed up on one device but not the other - not all things just some things. I think they finally got that straightened out (but if you don't compare every file how do you really know?). My general impression is that OneDrive is sometimes rather slow - just my impression. I use Google Drive for some things, but only because OneDrive, that particular day, didn't want to accept a backup file from a particular application but Google Drive, in each case, allowed my device to auto backup without issue. Like some others have voiced here, I much prefer to use only one cloud service like OneDrive just to keep things as simple as possible; however, with OneDrive (ordinary OneDrive not the business version) I've found it to be arbitrary from time to time in its performance.
