I'm not the fighting commander, but this looks like a pretty standard six-button controller to me. The two rows of three buttons are arced to match the range of thumb motion, and the molded grip looks to accommodate the thumb and pinky of the reverse-sandwich hold pretty well. I like how the L and R buttons are all present on the shoulders, instead of the two extra face buttons replacing them. I'm used to L1 and R1 being hard punch and hard kick rather than R1 and R2, but that's always easily configurable in whatever Capcom game you're playing.
Of course, nothing exceeds the Saturn-styled controller. I wish I'd picked up those when they were on the market.
