Let's face it, the 5S and 6 are almost the same phone. The only differences worth mentioning are: - Larger screen - Slightly faster CPU/GPU (5S is already fast) - NFC At the current price point, I see absolutely no reason to buy the 6. For $100 more, you'll get a whole lot more for your money. For $100 less, you'll basicly get the same phone, although it is smaller and you'll miss the NFC (Apple Pay is currently irrelevant for people who not live in the US or UK). So unless you're mainly focused on either NFC or a larger screen, I see absolutely no reason to buy the 6 at the current price point. I can think of a lot of reasons for recommending either a 5S or a 6S, but not so much for the 6. What do you think?
