Which cloud storage gives the most space free?

Google Drive gives 15 GB free, shared with Gmail and Google Photos, and is the easiest for most people. MEGA gives 20 GB free with encryption. Proton Drive and iCloud give 5 GB, and OneDrive gives 5 GB. For private files, Proton Drive encrypts everything so not even Proton can read it.
