Okay, so people are starting to throw out the word "opinion" as a defense to say that their argument is infallible again, so I'm going to dispute their "opinions" with facts.
Below is a list of characters organized by how well they did in tournaments and how often they showed up. Apparently, Meta Knight and Snake are quite a bit more commonly top placing than the rest of the cast. There's possibly more characters taking wins and top4s than in Melee, but then you've got the huge list of characters barely placing top8 and the entire 9 characters not even making it that far.
