Yes. iOS has better Apps. But iOS limits functionality of Apps. How long did it take to get Turn by Turn Directions native in our Mapping Program? You are limited into what some great overlord thinks you need to do with your iOS NC.
I didn't wait a single day. For $15 I installed Navigon MyRegion (superior in that it navigates you even with no cell connection and no pre-planning needed).
How long will you wait before Android's native maps app will actually use your contact's addresses as auto-completes when searching? Apple's maps have always done that.
Yes, you can find a specific detail where Android is ahead. And one where iOS is ahead. Those are the little things.
And if you think Google is not being an overlord controlling Android at all, then yes, Android is about marketing--successful marketing
The marketing: "Apple limits what you can do."
The reality: you can do TONS more with Apple than with Android.
As for customizing the OS itself--yes, Android is the winner there. At customizing the screen you see when you're NOT using an app. I think the importance of that is WAY below the importance of actual apps.
EDIT: The reason for this (and the reason a certain niche really should choose Android) is that Android tries to be more like a legacy computer. iOS aims to be different and BETTER than a legacy computer. Simplicity is part of that. It's why you don't have to manually processes on iOS, and why a new iOS device perfectly clones every setting and detail of the old one you replaced, and why we don't have malware on iOS. Apple's path truly DOES have a downside--but you can't have the upside without it, and it's a big upside. Make iOS more like OS X or Android and you'd gain a little... but lose a lot. Change is hard after decades of traditional computer habits, but I for one do NOT want iOS to get more Mac-like. Its flexibility has grown, and I'm happy to see that continue--but never at the expense of usability. Because power is both what you can do AND how easily. And the things Apple "won't allow" on iOS are a very small list. Porn? It's in the browser. Piracy? True--you must jailbreak for that. And then various system customizations... that are great, but don't matter so much once you're using your device for a task (running an app).
Android has the more useful apps, such as SwiftKey and Tasker. iOS has absolutely nothing as advanced as Tasker.
I've given you a BIG list of full-scale apps, outstanding and complex and powerful productivity tools that are iOS-only. And I specifically said I'm not talking about little utilities. You can't give me as large and as high-quality a list of Android-only apps. Real apps, not little system utilities.
Instead you've come back and named two little utilities, as though that somehow equals or bests the big list I posted. I think my point is proven

Yes, those are neat little system customizations. That's great, and you're NOT wrong to like them, but it's all they are. They don't answer my question.
Your emotions make you WANT Android to be better than it is, and I can understand that. You want the awesome iOS-only apps to not matter. Yet they do, all the same. Android is the best choice for some people anyway (those who care more about system utilities than actual productivity apps), just not for as many as want to believe it.
