I like my Titanium. It's a little different than the Machine Grey - it's got the metallic flecks that I prefer. I looked at a GT with the Machine Grey, but unfortunately I looked at it right at sunset and it looked "just grey" to me. I was in a hurry to buy (God rest my totaled Mazda 6) so opted for Titanium.
(ok, I can't make the image inline for some reason.)
