Not sure if they’re better. I want to say “no”, but honestly I haven’t done a thorough comparison. I used to have a Lumia 950 Windows Phone so OneDrive did automatic backup of photos and file and everything and was nicely integrated into the phone essentially. One thing I believe it allows me to do “automatically” is link to files in OneDrive in emails, so that the email itself never contains the files, just the path to the OneDrive storage - but I think it’s still transparent to the recipient.
I suppose one thing doesn’t exclude another. Many clients of mine use both Drive and Dropbox so I’m occasionally forced to use them.
