I play some of the characters you seem to have no clue about or are underrepresented so here's my post on some of those characters.
Peach: I've been a Minus Peach main for 2 years which is longer than 90% of the Minus scene. I hope to hell I've mastered everything she has, or at leat gotten close. She has a great item game, aerials with no landing lag (fair and bair) crazy kill power and solid combo game. She's not the best in the game but she is really good.
ZSS: ZSS is probably one of the more balanced characters in the game imo. She has really good , intricate, combos but they don't do as much damage as other characters have got. Dsmash, side-b and paralyzer are good for walling. A ZSS with a good item game is deadly.
Puff isn't explored very well because Fsmash is one of the best moves in the game. It kills, comboes into itself and other moves, covers large swathes of the stage, has little endlag, and is safe on shield if spaced properly.
Farkus needs to work on his non-fsmash game because a successful Puff needs to actually use other moves sometimes. Puff can combo all her aerials into rest (yes all of them) with proper setups. Puff's gravity and sourspot nair murder anyone who doesn't have an amazing recover like the PK kids and Falcon.
I like to think I'm the best of these 3 characters around so I have some say in how good they are but we won't know until I have Netplay.
