I dont care about android on a phone... but reading some posts, ios seems to be perfect, maybe too many apple fans here.
Android is actually pretty good, and both iOS and Android have their various limitations. I don't use Android enough anymore to really comment on it though... But one thing that I still really don't like on Android is the graphical user interface has a very slight lag (it can only be a few milliseconds), but it's very jarring for me... I understand that the next release will addresses this issue by moving the graphics stack to a higher CPU priority (didn't they say that last time?).
Also, as Amiga users we are used to tight Hardware/Software integration... Which the various Android vendors can't provide.
