It probably has nothing to do with technical capabilities, but more like productivity. For people who have lots of time and don't mind fighting around with problems, nonworking settings, slow/varying FPS, corrupted official OS updates, malware etc. Android might be a better choice but other than that it's really hard to image any rational person taking Android over iOS. Especially considering that the security level of iOS is on a completely another level when compared to Android.
It's almost the same thing why these days almost all developers and companies prefer OS X. Because it's the only one that gets the job done without unnecessary and non billable issues and still has awesome software support.
