Brian Tong delivered the goods: the direct comparison I was looking for.
..I'm a silver person anyways, classic, tried and true, and never regret it. The space grey the two times I tried it got tired of it sooner than later.
The midnight looks cool as heck honestly but the easy smudging would drive me nuts, and it looks a smidge like a non-Mac to me.
The space black however, even if it great reduces fingerprints, to my eyes really looks like a Space Grey 1.5
