In my case I like the further backup to the local storage as I found out, when I upgraded to my Note 4 two years ago, that the Cloud didn't backup all of my content properly. Fortunately, in my IT and phone upgrade paranoia state that I possess , I had the full contents backed up to my PC prior to activating the 4 so I was able to fill in the holes left by the Cloud. I would have lost some 20 contacts if I hadn't done the backup to my PC and at the time, most were critical for work.
I don't completely trust the Cloud as yet. Security can still be iffy at times and the experience with an incomplete backup just has me a little wary to rely on it 100%.
