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

Reads · Competitive PvP
Minimalist fencing duel that is almost entirely about out-guessing one human.
Fatal Fury Special leans Execution (Competitive PvP); Nidhogg leans Reads (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.
Nidhogg
Sword-height changes and dive-kicks need quick hands
Nidhogg leans a little harder on reads, though the gap is small.
Fatal Fury Special
Two-plane dodging adds a guessing layer to human footsies.
Nidhogg
Pure human duels of feints and conditioning
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fatal Fury Special
Deterministic; nothing hidden.
Nidhogg
Symmetric deterministic arenas
Fatal Fury Special leans a little harder on optimization, though the gap is small.
Fatal Fury Special
Punish routes and plane-shift tactics are learnable.
Nidhogg
Small toolkit, little to solve beyond fundamentals
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.
