It may be a minor quibble, but I found the DC controller to be rather hard on the hands. The edges were just sharp enough to be uncomfortable after a good round of Marvel vs. Capcom.
I quite liked the DC controller. Never felt the comfort issues you’ve reported on (but everyone’s hands are different).
That said, I do agree with your point about the fighting games. They’re definitely played better with arcade sticks (same is true for beat em ups on most systems though).
