I think it is a bit ridiculous to argue that Google ships "beta" projects as opposed to Apple never allowing whatever-things-you're-pointing-out into an iOS version when Apple issued a public apology for a core feature of iOS6 (Maps) and then went on to openly and repeatedly deride the skeuomorphism of iOS6 in their iOS7 intro (there are, of course, many other examples of iOS issues). Apple makes huge mistakes... and then corrects them (the Maps app in iOS7 is awesome, the skeuomorphism is thankfully gone, etc.). Google makes similar mistakes - arguably not of the Maps caliber, though - and corrects them (or many of them... the Camera app remains pathetic).
However, I'd argue that, overall, the two OSs are roughly on feature parity now; each has their plusses and minuses, but overall, you can do the same things on each. I'd further argue that a jailbroken iPhone is perhaps superior to an Android device, in that many of the perks of freedom that Android provides are then available under iOS.
I've developed iOS apps and Android apps for my company (nothing major), and there are reasons to favor one or the other at a given time; both are good development environments. So, since I've used both and developed on both, I know them both and am not going to bash either (as a whole - there are certainly parts of each I don't like).
That said, iOS7 was less significant than it appears (it's more like changing a CSS section of a web page than rewriting the backend server code), and KitKat has some deep changes in it (ART is one such thing). iOS7 might or might not overall be a greater change - I've not spent a lot of time dabbling with the API changes - but it's of similar scope overall, just biased toward the visual.
One thing that impresses me about Google vs Apple, though, is that iOS is a core part of the Apple business model. It is fundamentally vital to their business. Android... well, Android is just a neat little project for Google. Sure, they're moving more into that space, but it's not remotely central to their business. It's certainly becoming more important, and it's a very strategic part, but... I get the feeling that iOS has vastly more resources available to its development than does Android, and so I tend to favor Android, simply because it's so competitive even though it is at a disadvantage.
I'm likely going to get a retina mini. It's just too cool. I own a number of Android devices. My entire family aside from myself uses iPhones. I'm not interested in arguing why one sucks because the other does some task better.
Anyway, back on topic:
I continue to hate the Camera app. It is inexcusable, in my opinion, that it has remained so bad across so many releases.
I also hate having to manually scroll across home pages and the Applications pages instead of just scrolling along the bottom to rapidly get where I am.
Other than that, I'm pretty damned fond of KitKat.
