I don't think it's that rare... people often have multiple devices.
I have an Android phone and an ipad. It's very clear after a little use that the ipad is "snappier" (and animations are smoother etc), but iOS also feels very very limiting by comparison with Android. There are so many little things that Android just does right, that iOS...doesn't.
So which is more important, smoothness or functionality? I suppose it depends on the person and how they use the device... but really, I'd like both... :]
Besides the things iPhone copied blatantly from Android phones (Notification center, 'Today', Quick toggle settings panel, new multi-shot camera etc.), you have:
100 things iPhone 5s-5s can't do that Android can.
