The battle of Android and iOS will be a never ending siege. Fan boys from both sides feel like they both know it all, when usually neither have tried out the other OS properly. Before even trying out the other OS, they've already made up in their head that their OS is the best and nothing can beat it.
A YouTube user has put together a series of videos comparing Android and iOS. You could say he's biased but he has some very valid points in his videos. I've also used Android for over a year before going over to iOS and I still would say Android as an overall OS, is better.
