Android smartphone master race reporting in.
Android has widgets, true multitasking, more customization options, multi-user profiles, a wider selection of hardware, more powerful hardware, a better notification tray, the ability to sideload apps, support for Adobe flash, firewalls, ad blockers, themes, a system terminal, a more open ecosystem, free dev support, better console emulators, and more. Tests show that Google Now is also faster than Siri. iOS is like a console OS while Android is like a PC OS.
Fragmentation?
Root your device and flash a custom ROM. Rooting is easier that Jailbreaking.
Better UI?
iOS has only had a "modern" UI since iOS 7. Android's UI has had a modern look since Android Ice Cream Sandwich, which came out way before iOS 7.
Games?
I have emulators for NES, SNES, Genesis, N64, GBC, GBA, DS, GameCube, and Wii on my smartphone. All of them, except the GameCube and Wii emulator run flawlessly. Have fun playing Angry Birds.
App selection?
You can only run apps that Apple approves of. I can download the free Android SDK, write myself my own Android app, compile it to an APK, and sideload onto my phone. Try that with iOS. There's even a IDE that'll run on an Android device natively, allowing you to develop and run programs all on the same device.
Enjoy your inferior operating system, iOS peasant.
