I am a happy user of paid Dropbox, and I think many person are the same as me. For me, OneDrive and Google Drive are not enough simply because of their terrible sync system. Back then when OneDrive was just launched the speed for me was absolutely horrible (like <100KB/s). Sure, I'd like if I could just buy space as I grow, as I remembered it was a hard decision to buy 1TB (back then) when I only needed 50GB. I currently have >600,000 files in my Dropbox. I don't know if other system can reliably deal with this many files, Dropbox has proved it to me that it can deal with my files on Windows, Linux, and macOS.
