If I ever will experience a file loss on iCloud I think I won’t even ever know the way it’s designed and the way it’s documented and the way way Apple deals with it even after reporting an issue.

Unless you deploy another tool or service to keep checking whether everything has been a file loss or inconsistency inside iCloud. Yes, it’s that opaque!

On the contrary on Dropbox I know exactly what is going on and there are features to revert a change.
