I like ALL the iPhone 6/6 Plus colors as well. I actually didn't make up my mind until a day before I went and purchased my Space Gray 128gb 6 Plus. One of the main reasons I choose the "Space Gray" color is because it matched the Black Apple Product Leather Case the best, and I liked the way it fits/feels as it appears to be part of the iPhone itself (I always wanted a leather back phone since the Blackberry 9000 days...SMILE). I had the Gold 5s and I also liked All the colors of those iPhones as well, but the GOLD was new and different at time of release for that particular iDevice. I'm happy I went with the Space Gray color and the Black Apple Leather for the "BlackedOut" look, but ultimately you are going to have choose a color for yourself and your needs/wants. Remember you will be the one carrying it around 24-7-365.
Edit; I see you went with the GOLD. Good choice. I personally think these are the type of iPhones you couldn't go wrong with any of the colors....IMHO
