Long story short: Fox in the right hands is a beast. Zero Suit Samus is a disadvantage, and Marth a slight one, but it's no "lol" matchups. He has quite a few of those, though. Hence he's Mid Tier, not High Tier.
Frame 3 is, by the way, extremely fast. There's almost no attack that comes out faster than Shine.
