Two iPhones released together: the times are a changin'. And that means you have to make a decision. Now for some of you, that will be easy: you either want the best that Apple has to offer or you're on a tight budget and don't need the fastest CPU or a fingerprint sensor. The iPhone 5s replaces the iPhone 5 while maintaining the same iconic and stunning metal design.

Read and watch our smackdown to decide.
