Combined with bad security practice from OEMs, preinstalled bloatware, app fragmentation (I love having Samsung "Phone" app and stock phone app at the same time) and customer service (try replacing your phone battery and compare the experience of ubreakifix and Apple store), I don't see a reason to go Android.
(P.S. people who cannot afford the latest iPhone can always purchase a two year old used/"refurbished" phone. It's a solid choice and many people do that. The fact that you can now add Apple Care to 4 year old device makes this more viable.)
