On its own, I'm personally a big fan of the black over the white. Probably an artifact of my years in the old beige PC days of the 80's and 90's. I was never so glad to move to black PC cases.
My only concern with it is of course ALL of my other test equipment is white/beige, so having one black scope sticks out like a sore thumb. But believe me, if I could snap my fingers and everything change to black, I'd do it in a heartbeat.
