Which color should I buy? (iPhone 5S)?

I am about to get the new iPhone but I don't know which color should I buy.
so I decided to try your taste, if you were me which iPhone would you choose, the space gray or the gold color and forget the white color. Just choose a between these two colors: space gray and gold
thanks

Space gray, a lot more potential with space gray to color coordinate with your case, plus space gray is a better color, do you really want to be the person with a gold phone? Gray shows more class
