I have iphone 4 and upgading can somene say what's bettr on 5s than 5c?

I like the look better and finger scanner on 5s but which should if moneys no problem

Well the 5c was deliberately made cheaper that the other iphones hints the ugly plastic outside so iphone 5s definitely

They're iPhones they are almost exactly the same but the 5s is nicer without that cheaper body and you can always get a case to cover the dodgy colours.
