They both sound fantastic. It's like Cadillac vs Lincoln, or chocolate vs vanilla ... they both have their loyal buyers. Taking sound (subjective term) out of the equation, here's just looking at a few practical sales incentives:
1) Price - Korg wins
2) Size - Korg wins
3) Vocal Processor - Korg, hands down

So, as history has shown us, People will buy what they like. There's an A** for every seat, and I'm sure the Genos will be a success. I just think you'll see more Korgs on stages. Just my thoughts.
