Yes, gold is still the best and everyone who says otherwise is jealous.
The 6 and 6+ look the best in space grey. Gold seems to look tacky now.
After a while the space grey will show it's age. The silver, less so.
Who cares get it if you like it. I had almost every iphone since the 1st gen and all were either black/silver/gray of some kind. I'm going gold this year for a change. I thnk it looks beautiful the Verge hands on video won me over.
If you look at the delivery dates right now, it looks like the silver is the most popular.
