It is true. I think the difference is that I am talking about aerial approach as opposed to simply the aerial game in general.That's not true. What affect's aerial approach is not horizontal movement but the speed at which aerials come out. It's not difficult to dash -> SH -> aerial when you're right in front of them. That requires almost no horizontal movement. Notice how MK, who has arguable the best aerial game of all characters, is in F Class.
I also was generalizing somewhat since I said "many characters" and not "all characters."
Meta Knight has a good aerial game, but his aerial approach is sub-par compared to most of the characters in S and A class. It's for this reason that Donkey Kong is one of the harder matches for Meta Knight. Meta Knight relies heavily on grounded approaches, and DK really stuffs grounded approaches. MK certainly has a good aerial game once he gets the ball rolling, but he gets the ball rolling best by approaching from the ground.
