Do NOT get an iPhone. I have had an iPhone 6S for about 2 years now and it has been a love/hate relationship with it. I love it because I have used Apple products a lot, I am used to the interface of iOS and I have a lot of music on iTunes so getting everything synced was easy.
I hate it because my phone has been bricked and needed factory-reset 4 times because of an iOS update gone bad. Over time I have accumulated about 20 hours on the phone with AppleCare tech support because of other issues. I have also had iTunes updates erase all my music instead of sync it before, and just recently when I tried syncing it, it put 4 duplicates of every song on my phone.
Plus, unless you shell out $50 on a heavy duty lightning cable, the Apple lightning cables are cheaply made and fray like a Christmas tree at the connectors within a month or 2 of average use.
I am planning to finally hop off the Apple bandwagon, switch to Android and get a Samsung when my contract is up in a few months. Plus, Android supports M4A so I can drag-n-drop & play all my iTunes music on it!
