What else is there about Android that keeps you there other than screen size? Just curiosity.
Customization, flexibility, and notifications.
1). I prefer the notification system of Android, hands down. Not only can you customize what's in view, I can swipe aside any individual notifications I don't need or clear them all, control whatever audio I'm listening to, so much more function and flexibility. Pair it with the LED and it's awesome. I'm contemplating trying a Moto X so I can try out Active Notifications which seem to take it to any even better level.
2). Customization options are nearly endless. To give some perspective, on iOS I can choose my wallpaper and arrange my app icons almost anyway I like. On Android, I can do so much more. For instance, to start, I've setup my lockscreen with a custom unlock widget that allows me to directly launch any of 18 different apps.
Once unlocked, using Nova Prime launcher, I have 5 different home screens (can have more or less, whatever one prefers) arranged with a collection of app icons, folders, and widgets. I can have app icons anywhere I like (i.e. only along the bottom, for instance) vs. them automatically snapping to the next free position on the screen as done in iOS. I also have a dock that scrolls independently from the home screens--I like having 3 sets of 5 icons in my dock. Again, beauty of Android is I can have more or less, almost whatever I want. I don't use a ton of widgets but I like having one with my calendar quickly viewable (and editable) and another with my Twitter feed. Lastly, I have a custom theme that changes the appearance of all of my icons.
I also run a couple of other apps that, in conjunction with the gesture options provided by Nova Prime, let me navigate around my phone without ever having to touch my home button, multitasking button, or app drawer, all via simple gestures.
3). In addition to the flexibility of customization, I can setup whatever app I want to serve as the default app for functions. I can choose what browser opens when I touch a web address, what app to open when I select a photo, what app opens when I touch an address, etc. Also, when I choose to share something, I can select any appropriate app vs. the few that iOS may allow. And while I never had problems using iTunes to coordinate syncing of data and media, I prefer having the flexibility to use something as simple as drag and drop or an app like AirDroid to quickly do it wirelessly.
Oh, and another example of flexibility. Similar to the trusted Bluetooth device element of the Moto X, I was able to set up my HTC One to not require my lockscreen security (pin number) if it's connected to my Pebble smartwatch.
I'm sure I could come up with a ton more but this alone illustrates why I prefer Android, right now. As I mentioned, there are still elements of iOS that I like--the consistency between OS and apps, the simplicity of certain elements, the backup functionality and integration with other Apple devices. However, it's just not enough to compensate for everything that cannot be done.
Again, this is all just my preference and I can certainly understand someone seeing it differently and preferring iOS.
