Can I vote for neither? Seems like every other car on the road is some shade of white, with most of the rest a shade of gray. Pick an actual color - live a little!
That said, I prefer plain Alpine white to the metallic white. It's $550 cheaper, and touching up/matching metallic white is a horror show if it is ever necessary.
And THAT said, if you do choose the metallic white, IMHO the brown top looks much better with it.
