storage for uploads from my phone if I allow Google to compress the images and the app works well on my phone.

Dropbox for my work docs. I had syncing issues with Google Drive several years ago so I moved my docs to Dropbox. Dropbox has been rock solid for me with nice sharing features and it's available on most every platform.

Backups only: Crashplan ($5/month) to backup everything. I probably don't need it but I have it for redundancy. I also use TimeMachine for local backups.

OneDrive - it is actually unlimited for me because I have an Office 365 account. I may move my Dropbox files over to OneDrive but I haven't got around to doing that yet. I'm pretty impressed with OneDrive.

I'm slowly moving away from Google because of privacy issues. I haven't given up my Gmail account yet but that might happen one of these days.
