So I like this list mostly and think you are doing a pretty good job here. But I am wondering about the criteria for the Punish K.O.s category. What I am picturing for this situation is if someone misses approaching with a relatively laggy attack and doesn't space properly (say Ike's fair and the sword tip land right in front of you) or uses a helpless inducing recovery poorly (foxs upB and goes way up past the edge) , how easy it would be for your character to capitalize and get a K.O. out of it.
Anyway, so that's my idea of it, and feel free to correct me if I'm wrong. So the two standout ratings that I disagree with would be Fox's D and Pit's B. I would say Fox's hyphen smash is definitely one of the best punish K.O. options in the entire game, and I'm not sure how pit would have a B, though his Fsmash is decently powerful as is a strong Bair, but I would argue they aren't nearly good enough to warrant a B. I'm guessing he has the B because of his shield, but that really only gets you punish K.O.s on a bad recovery, not really failed approaches.
Maybe I'm interpreting the category the wrong way, but that is the impression I get from your description of it. But on the whole, awesome list.
