I find ios to just be stale, maybe it's a "grass is always greener on the other side" sort of deal but it just seems to me like there are more interesting application options on Android.
I agree, I don't think there's anything inherently wrong with it (ios is great for certain people) but I know when I fiddled around with my gf's 5 it felt like the exact same phone I'd been using. At that point it was felt like if I'm going to be throwing down a decent amount of money on a phone I want it to at least be something new.
