I got to play a couple against AndyG and had a money match with Blackwaltz at CoT4; I've come to the conclusion that the trick to beating Olimar is approaching him. You have to outsmart your opponent and read their actions to get past Olimar's near-perfect camp ability, but once you do he's actually easy to beat up on and kill.
The Snake vs Metaknight matchup actually heavily favors Snake on paper; actual-practice may vary depending on player skill. If you look at the kill percentages (85% with no DI on Final D with a fresh up tilt; something in the mid 90s with DI IIRC) and how many of Snake's moves beat Metaknights and how easy it is to beat them then you'll have an appreciation for how hard Metaknight has to work to win that match. The "omg you can gimp him so easy" argument is actually taken into account here; Metaknight has to get those early kills to be able to make the match almost even. One jab to forward tilt from Snake puts Metaknight at roughly 1/3 of the needed damage to kill him. Metaknight actually has to work very hard to beat Snake.
