I was in an Apple store yesterday for the first time since they announced the 6s, as there isn't one close to me (at least an hour and a half out.) Anyway, I wanted to see the color in person. I don't hate it, but it definitely looks pink to me. With that being said I like it way more than the original gold. Also, go with whatever color you like the best. It doesn't matter if you're a guy, girl, gay, straight, whatever. Just get the color that you like.
I personally wish Apple would have added another black bezeled option instead. Ideally black on black would probably be my go to, but I guess Space Grey is the best we'll get. I think a navy color could be good. I have a White/Silver 6 Plus and while I do love the color I think I'm learning I really just prefer a black bezel. I went Original > Black 3gs > Black 4 > White 4s > Black 5 > White 6 Plus and I think I'm just learning black bezel is more practical.
