This is largely a comparison between the management styles of the two platforms. (FWIW: I've owned by iPhones and Androids.) On iOS, the UX guidelines are well defined and Apple forces apps to stick to them; Android is the Wild West. On iOS, nearly every app is straightforward but limited; on Android, apps can do whatever the hell they want. These two constraints lead to different outcomes. Two examples: NYTimes is much simpler on iOS but richer and more confusing on Android; Flikie HD isn't possible on iOS but works on Android and has an incredibly confusing interface. Reminds me of Mac vs PC all over again...
