I agree with
@4wd Why not use both?
There's nothing to stop you using more than one. I have OneDrive, Creative Cloud, iCloud, and Dropbox. I'm sure most people (not just here on
Talk Photography, but anywhere else) are likely to be using two or three or more different cloud storage services.
If Google Drive is having problems, you could use OneDrive, same with if OneDrive is having problems, use Google Drive. Or you could use one for business but the other for personal, so your files don't get mixed up. And consider this: Since most cloud storage could be used free to start with (with limited storage space which is just temporary), you could field test each one in turn, when you finally decided on which one you feel is more suitable, you can always transfer the files from the service you don't want, to the service you want.
For example: Try Google Drive for a couple of months, then try OneDrive for a couple of months. If you decided Google Drive is better, just move your files from OneDrive to Google Drive (or the other way round if you feel OneDrive is better).
