I'm actually pretty on the fence for this one, I own both the white and the black and for me PERSONALLY both has pros and cons example being the white would yellow over time which I personally don't like but some people like it as it makes it more unique to them. I have the white blanks on my white HHKB now and the white printed on the black HHKB and I think this looks the best and I even have the red/blue control/esc pack on them, as you might have seen from the HHKB Pro 2 thread. I think the white looks ok with stock white printed keycaps and white blanks. As for the black I think most of the combinations look ugly except for the white printed caps on it, there's just something about the two-toned color paired with the fine black printing that goes so well with the black hhkb, I'd say the black blank + black does come in as a runner up in terms of looks.
