Note 4: I dropped $750 on release day for it with Verizon.
There are many reasons why I personally chose Android over IOS. Here are my top ten reasons in no certain order:
1) SD Cards are allowed for removable storage
2) Removable battery/battery life (3220 mAh vs 1810 mAh)/ulta power saving mode
3) 4k Recording/16 Megapixels (vs 8 on iphone)/3.7 megapixels (vs 1.2 on iphone) front facting camera
4) Corning Gorilla Glass 3
5) S-Pen
6) Application such as Foxfi(tethering on an unlimated data plan), emulators, flash and such are aviable without root/jailbreak. Also, you can easily download .apk without root.
7) Bigger Screen by an inch/more pixels per inch/better resoultion 1440 x 2560 pixels (vs 750 x 1334 pixels)
8) Super AMOLED
9) Mult-tasking/spilt screen.
10) One hand mode
