The problem with Supercade is the delay. There's significantly more delay, especially for 3rd Strike. Just trying to parry in 3S on Supercade is a night and day experience. The timing is entirely different. Which is why everyone rightfully so trashes Supercade. 2DF was surprisingly better than GGPO, but had some sound bugs. What happened between 2DF and Supercade only Damdai can say.
