I have been using iPhone since iPhone 4 realsed. I do use android the plus point of havinh an iPhone 5S is it doen't lag it gives you smooth experience and best right now you can update you iPhone 5S to the latest firmware that is iOS 10.
It looks nice with sleek metal body and very comfertable whlile holding the phone it is not slipery at all and yea the camera. The front faceing camera is nice way better than regulat android phones. and the rear camera is so awesome sometime I take picture for professional perpose. The ips display gives you true color experience its not over saturated unlike AMOLED display. All in all if you are thinking of buying an iPhone and you have a budget arount 20k than I would recommnad you to gove it a shot.
