Sorry if this has been asked a billion times, I tried searching the forum but there's a lot to weed through and couldn't find a specific answer! If you want to transfer all apps/data/music/contacts etc from your old iPhone (5S in my case) to your new iPhone (6S+), is it better to do so via an iCloud backup or an iTunes backup on the computer? Is there any difference between the two? Does it matter if 90% of my music library was not purchased via iTunes? Like will iCloud only backup & restore music purchased from iTunes? I haven't transferred anything between iPhones in a couple years so I just wondered if any part of the process has changed with the introduction of iCloud and with iOS 9; I just want to do what's easiest!
