Brawl Falco > Melee Falco
Smash 4 Render Fox > Every Fox before it
The designs are fine and totally fit the nature of the StarFox franchise. They're distinctive without going too far into the creepy or overly humorous.
Brawl/Command Falco's good, but I don't see any reasonable argument for Brawl/Command Fox over SF643D's. While Melee Fox's general head shape doesn't repulse me, I get how people are creeped out by how it looks like taxidermy. SF643D has the more simplistic/cartoonish look without having a flat, corgi, too-far-spaced-out-eyes Brawl look.
The general approach to character design in Command wasn't the problem; them being more cartoonish compared to past games was fine. It's just Fox that got hit with that ugly stick.
