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

Execution · Competitive PvP
Fast arena-fighter execution plus guessing games against a human opponent.

Execution · Competitive PvP
The beloved upgrade of Fatal Fury 2 whose two-plane stages add a dodge dimension to classic footsies.
Dragon Ball Z: Budokai Tenkaichi 3 leans Execution (Competitive PvP); Fatal Fury Special 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.
Dragon Ball Z: Budokai Tenkaichi 3
Combo timing, dashes and beam clashes demand fast hands
Fatal Fury Special
Strict motion inputs and combo timing typical of 90s SNK.
Fatal Fury Special leans a little harder on reads, though the gap is small.
Dragon Ball Z: Budokai Tenkaichi 3
Versus humans, baiting counters and vanish wars is prediction
Fatal Fury Special
Two-plane dodging adds a guessing layer to human footsies.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Budokai Tenkaichi 3
Almost nothing hidden once both rosters are known
Fatal Fury Special
Deterministic; nothing hidden.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Budokai Tenkaichi 3
Character tiers and combo routes form a learnable layer
Fatal Fury Special
Punish routes and plane-shift tactics 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.
