Marth beats Snake 55-45.Idk about DDDs cuz I can easily take anyone out using him(probably cuz Ive had loads of practice against him) as for a Marth ditto match-up, it can get pretty annoying. Especially wen your opponent is thinking the same and we both do counter which leads to nothing. I'm gonna have to go with Snake though. He has good power and swift tilts that can easily take out Marth at a early %. His uptilts and ftilts get the job done.
Marth's hardest matchup is Mk. Mk just destroys Marth.
