I ordered this on a whim and got a cheap set of keycaps off Amazon for it, but now that I have it put together (plastic switch plate, tape modded, gateron cap golden yellows, double o-ringed keycaps) it is sounding and feeling really good. The keycaps were a cheap but they are bright and fun. I might make it my "throw in a bag and take into the office" keyboard.
Slightly better ergonomics, mostly. Kinda forces you into better typing habits overall also since its harder to be tempted to reach too far with one hand to hit the keys the other hand is responsible for.
