My both mobile & tab are based on Android OS, but different verions (KitKat & JellyBean). To be honest, I never tried out IOS, as it's too way expensive for me to afford, but I saw it at some school mates, and it looks quite flexible. However, if there would be to make a top of the OSes available for mobiles, I would place Android on the first place, IOS on the second and Windows on the last (I like its design, but it's quite limited).
If you would like to purchase a new mobile, what's your budget, first of all?
