Tale of two X100s
Good comparison! I love my black X100. The IQ compares extremely well with my X-E1, but I have to admit I defer to the X-E1 when I'm going out to take photos. I think the only reason I'm holding onto the X100 is because it is so beautiful!
I have XE-1 and 23 1.4, and that combo definitely has the upper hand in terms of IQ by a wide margin.
But like you said, the black X100 is so beautiful to look at
