O_o' I might be switching now. But from the lab, it seems F Kouma deals the most damage with the least hits.
Edit: After watching it again..H's mixup options and mobility absolutely dominate C's. His pressure options seem to be better as well. Is that the 22B he's doing to dash up into the air to the airthrow? Jeez, H is so much more efficient than C. Thanks for linking this.
