I recently stopped using Dropbox and switched to iCloud Drive as well. I had exceeded the 3 machine limit and was ready to pay for upgraded Dropbox but decided to compare options first. In addition to costing the same as Dropbox, iCloud drive allows me to do full system backups and restores to/from iCloud for iPhone. I don't know if this is unique but I like it and need to figure out how to get my two MacBooks to do the same thing.
