In My opinion Android is more open source and user friendly. and wast connectivity range for different kind of devices.
Android is upgraded faster then iOS. you can get millions of apps games on android freely. that you can't get on iOS.
you can attach your Printer with Android and connect it via NFC, BT, DLNA, Direct WIFI etc ...
You can safe your data on any other PC laptop etc..
You can share things easily
You can customize your device and root your device easily
exchange data even other brand models. no worries.
But lack of security as compare to iOS

iOS is too limited to transfer data. even BT is not connect any other device except iOS.
Upgradation is too lazy and limited.
almost same visual graphics and interface if you see iphone 4 5 6 ipod 4 5 etc..
you can not copy data to your pc without internet or specific apps like itunes icloud etc..
too difficult to root or jailbreak.
no custom Roms
Lack of hard and soft buttons. only one button to do almost all. so that's why many many apps was working on background eating RAM and Battery.
non removable battery that's why high prices go down even after one year.
if any damage. too difficult to find out device parts and mechanic.
One best thing is that. sleek look and tuff security. protect your data as in past like Blackberry.

So this was my analysis. Hope you like.
