Um, not sure if you still need the info, but here is my opinion ( i have both iphone6 and Samsung galaxy note 3)
I recommend a phone with an android OS.
I use the note3 for everything i use my PC for. Cannot do the same with iphone. Even if you're not plan to root your device to customise it, i still recommend an android.
In android there are plenty of good filesys apps, (in iphone i have the user's nightmare, called itunes. For me the main disadvantage of apple us that they dont have a folder system (which means you can transfer data only thru itunes)
You've been already told about the glass screen - iphones are extremely breakable and high maintenance, and i am clumsy, so I've already repaired the screen 2x times in 6 months (while the note 3 i use more often has no skratch in it)
The iphone SIM is not standard and can be removed only with the special SIM removal tool.
No NFC in iphones, also cannot add SD card (not that many ppl need more than 32/64 GB. I do, so it's good i can add in my galaxy 🙂 )
The autocorrect is dumb, you cannot tame it, only disable.
But the camera is better in iphone, (though the voice recording in video sucks) same with battery life.
