iOS only! I think it's really easy to use and I like their design! However I do not doubt that Android is quite good but iOS will always be better. 
This kind of statement is basically too wrong to even be wrong.IOS is already way, way worse as you can see from the very existence of this thread.
IOS refuses to support BTC apps. Hence IOS can not be better, let alone "always be better". If they decided tomorrow to allow BTC apps they could still never achieve status of "sometimes being better" because they could disallow such apps at any time. They suffer from a top down control model malfunction.
Probably just an Apple fanboy with little to no experience of other devices.
