I think for me the cap quality would be the deal breaker for me. I have a WASD V2 and the ABS caps are pretty crappy to be honest.
I used browns for a long while, and now I'm using clears at work, and if I'm honest, I think I prefer clears for extended typing, but for general use browsing and things, with occasional posts, I probably prefer browns.
I also like the huge amount of backlight customisation options on the Ducky. So I would say Ducky.
