I hate the pink color, and the gold is likewise ugly, in my view. That leaves silver (which pretty much matches the rest of the Apple Mac line) and space grey which I find quite attractive as well as unique. Space grey it is.
My 2015 MacBook was Space Gray. But after selling it, I decided to go back to Silver for the new 2016 model. It's just the most timeless color. Also... the Space Gray definitely picked up fingerprints easier from what I have seen so far.
I went with silver. After owing all gold iOS devices, except my watch which is stainless silver, I bought the iPad Pro in space gray for a change up and it scratched way too easily. If the iPad was silver the scratch would have barely been noticeable. So yeah, went with silver for the MacBook and next iPhone is going to be silver.
