Ryu, Game & Watch, Bayonetta, Mega Man, and Wii Fit Trainer are the best as far as translating the characters from their source material. Pretty much all of their moves are taken from their games. Unfortunately, I'm not interested in any of those characters even though they did a good job implementing them in the game.
Fox and Captain Falcon they actually did an okay job on for having very little source material to work with.
Donkey Kong imo has the worst moveset as far as having a lot of source material to take from and Sakurai completely ignoring it, with the exception of Gandondorf being a clone. It was completely out of this world that it took him until Smash 4 to get a roll attack, his signature move.
The only things that I don't think came from AC on Villager's moveset are his jab and his up-b, and even then, it's possible that they're based on the NES games you can get in the original N64/GCN AC games.
He did an okay job on Villager's moveset, but imo what keeps him out of the running is: bowling ball isn't a piece of furniture (although a ball return is), Villager never uses a stick for anything, watering saplings doesn't do anything in the games, parasol is kind of unreasonable as an ftilt and would be more reasonable being spun as an upair or up tilt, nair is made up, and Lloid is a character from the Animal Crossing series and not a disposable rocket.
Overall Villager has one of the less-terrible movesets in this game though. lol
