Falco's combo game is superior to foxes in everyway. Do you never play as fox? and for a split second wish you were falco to get that extra height for a killing bair? Do i need to mention lasers? they set up into all smashes, combos and grabs if you want. Falco is fast ENOUGH has more stage control than fox and is a danger basically wherever he is on stage. Also his bair is way more deadly due to better air movement.
Marth is just hellish for every character i don't want to speak of it lol. The sword is too long.
Fox dies more than falco. For 2 reasons one falco isn't as fastfalling. The other his midair jump sucks and from there his recovery options are horrible. Falco wont be dying as much. His shine isn't as useful as falco's i feel. His gun isn't as useful as falco's. I don't think his longer dtilt, powerful upsmash and faster speed compensate for all of falco's advantages.
I feel captain falcon is better than peach. Because falcon does better against icies and jigglypuff than she does. I could be wrong i just feel like there's nothing i can do as peach in those matchups, i don't think peach does very well against any of the top tiers whereas falcon has a much better shot.
I guess my list is more about viability, donkey kong get's ripped to shreds by falco, fox, sheikh marth and falcon basically all characters have horrrible things they can do to him. Mewtwo doesn't need to approach he has decent grab range and shadowballs and his bair outranges marths sword. His down b can lead to a kill. If you pick stages with low ceilings such as yoshi's story you can upthrow them to death at like 70% guaranteed. Once you get into boxing range mewtwo becomes really good. All of his tilts are good, his uair is amazing has awesome range and power and can kill. his bair outranges alot and can kill and combo, his fair kills and combo's his dair... lol can be a pro spike... at best. He can kill from a distance has decent throws, has a very safe roll a large shield he isn't getting gimped has an amazing recovery,
I truely feel mewtwo is better than people think.
Yoshi m2 and game and watch better than dk? I believe so. Donkey kong has alot of easy to read options and if he makes a mistake he get's punished very hard for it. His tilts are slow save downtilt but i think that's punishable on shield. Game and watches fair alone make's donkey kong life hard it comes out quickly and if spaced right can't get punished, gaw has no real weak spot to aim for he may be light but his disjoints and combo's are all very solid. Yoshi is very underated imo, all his smashes are better than dk's he can double jump through smash attacks until like 100. He has a projectile unlike dk and all in all is just less readable, he's not slow and despite having no second jump tends to last a long time. Also gaw has judgement 9 which is quicker and more powerful than any of dk's moves : D.
