Many Mac and iPhone users I know use both; probably because both are free at the entry level. Jeffrey Mincey uses Dropbox the most. Why?
Apple’s iCloud– via Files app on iOS and iCloud Drive on the Mac– has only improved the past few years. That’s good. I use it. I like it. Dropbox is better where it counts. Speed and reliability. And the latest iOS update allows file navigation on iPad– File app-like.
I tried the iPad version today. Very Files app-like, indeed.
