The reason why I have always stuck with the white/silver from the iPhone 5 is because I like the clean look it has. Granted, the space gray is sleek, I still like the white/silver. Especially on the 5s when I had it. Just loved the silver ring around the fingerprint scanner and the silver chamfered edges. The main reason I like the white is because of the unique boot screen. The black Apple with the white background instead of the white Apple and black background that is found on the space gray models and all previous iPhones before they had the white option available.
