head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Competitive PvP
The beloved upgrade of Fatal Fury 2 whose two-plane stages add a dodge dimension to classic footsies.

Execution · Competitive PvP
The N64 original that turned Nintendo mascots into a percent-and-knockback platform fighter.
Fatal Fury Special leans Execution (Competitive PvP); Super Smash Bros. leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Fury Special
Strict motion inputs and combo timing typical of 90s SNK.
Super Smash Bros.
Z-cancels and DI demand fast precise inputs despite simple controls.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Fury Special
Two-plane dodging adds a guessing layer to human footsies.
Super Smash Bros.
Edgeguard and tech-chase guessing against adapting humans decides stocks.
Super Smash Bros. leans a little harder on variance, though the gap is small.
Fatal Fury Special
Deterministic; nothing hidden.
Super Smash Bros.
Item spawns add randomness; tournament rules strip most of it.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Fury Special
Punish routes and plane-shift tactics are learnable.
Super Smash Bros.
Stage positioning and percent-based kill setups are learnable.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
