I've seen several people arguing about which method is best to get to the iOS 9 GM from the iOS 9 beta's, aside from just updating to it without restoring at all. Various sources claim that restoring to the GM, and then restoring your data via an iCloud backup is better than just "updating" to the GM from the beta's, but isn't this basically the same thing in the end? What I mean is, doesn't restoring from an iCloud backup basically put the same "junk" that is leftover from the beta's back on to the phone, the same as just "updating" from the beta's to the GM would? Just wanting to get some clarification on the issue. Thanks.
