I'm not a fan of overly slick experiences that appear to have read my mind, so although I have an Android device, I have a de-bloated custom ROM, plus I've frozen a lot of the Google services (google now, search, etc) using Titanium Backup, as I prefer to search (in Opera Mobile Classic) using DuckDuckGo.
I use XPrivacy to lock down anything that I am even vaguely suspicious of, and I rarely install new things anyway.
My phone has incredible stamina (RAZR MAXX HD) and a great form factor, and I can just dump any files I want onto it or the 32GB microSD card in the side at will (which I regularly do for shuttling large files from work to home).
I don't see what iPhone could do for me, other than cost me more, give me shorter battery life, and force me into an incredibly claustrophobic experience.
