I use Google Drive and iCloud on Mac. I sync my files and folder tree with Drive and sync my photos, messages, etc between apple devices with iCloud. As a Gmail, Doc user I found this to be the most efficient way to pick up work between devices. As an iPhone/Mac user, the iCloud sync simplifies life. Drive comes with 15GB of free storage, and if that's not enough you can upgrade to 100GB for $2/mo. You can upgrade iCloud to 50GB for a dollar a month. The only advantage I see Dropbox having over these two is if you are a designer, or need to store and transfer large files on the regular.
