I have to say that some iPhone apps are higher quality/better than Android apps. Pandora is an app that comes to mind. It has a song progress bar in the iPhone version. Not on the Android version. The differences are small, like that example, but still present in a lot of apps. Another example is, until just very recently, our Facebook app (on Android) was pathetic compared to the iOS version.
But, at least, our apps scale between phone and tablet a lot better. If you try loading an iPhone only app onto an iPad, apparently it gets really blurry because of the resolution difference. I've not seen that between my tablet and phone.
