I wouldn't say I'm being closed minded when I say they just have superior tools. I think that MK is a hell of a character, but Fox in particular is so much the skilled players character, it's hard to compete. Shine, by itself, is so versatile and powerful a tool that it can dictate the characters interaction with blocks of the meta. That's not even considering the rest of his tools and how he's largely designed to be the character that works better the better you work. On a theory crafting level, Fox is literally a dream come true. I can understand placing MK high, but Fox, and Falco to a lesser extent, are just a fighting game players wet dream, while MK is solid as hell, but doesn't have the design to fill that same niche.
