On android you have way more customization options, improving both it's practical uses as well as aesthetics beyond anything on Iphone. Much easier on android to get almost any app for free if you don't want to pay for it.
You can also install custom roms and add cerberus for security. Cerberus allows you to turn your phone on remotely, take photos which find my Iphone does not, and it can also do everything that find my Iphone can do such as tracking, wiping data and so forth.
If your phone is rooted viper4android allows options beyond any app on Iphone for audio. You can use the same charger you've had for every other android, it uses a standard 3.5mm jack for audio instead of Iphone's lightning jack meaning if you have a really good headphone for gaming and other things you can still use it on android, but not on your Iphone. Almost everyone uses their phone predominately as a portable music player on and everyday basis.
Still no SD card slot for Iphone.
