For me, the space grey which does not have any contrasting ring on the home button somehow makes it look very plain, I love the black but the home button which remains all black as well is making me think twice.
As for the gold, I think it looks alright when playing around with it at an Apple store but I don't know if I will regret my decision or not after a while.

Some people love that uniformity in color, It's like a clean slate, almost mirror like piece of brilliant technology. It gives out a sleek and elegant vibe to the user but the user has to make sure that the surface is always finger print or stain free.
The gold looks tempting at first look which prompted my wife to select it. She was using a clear casing for the first 6 months and then just switched to a color opaque casing but then again, different people different perception. You may actually love how it looks more than you know it =)

Would be fun if Apple adopted iPod Touch colors for iPhones - I like that new blue on the 6th gen Touch

iPhone 5c attempted that and I don't think it is a very good move. Sure, it's fun to look at but can you imagine if people are bored with classic colors such as Black, White and Gold in just a few months, seasonal colors would wear off faster than you can blink. Then again, you always have the option of colorful casings for that.
I think Apple has already done a very bold move by releasing a Pink (Rose Gold) iPhone but as you can see, even that, it is a very subtle color. the iPhone is not meant to be fun per se. there's always a perception that iPhones are very corporate based. I cannot imagine Warren Buffett carrying a green iPhone XD
However, having that option of choice is a nice touch but will significantly increases the production workload for least popular colors and may even pump up the operating costs.
Besides, it's always Apple's style to choose for the user.
