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
The 2011 reboot that returned Mortal Kombat to brutal 2D fighting fundamentals.
Fatal Fury Special leans Execution (Competitive PvP); Mortal Kombat 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.
Mortal Kombat
Combo execution and punish timing
Mortal Kombat leans a little harder on reads, though the gap is small.
Fatal Fury Special
Two-plane dodging adds a guessing layer to human footsies.
Mortal Kombat
Human opponents adapt; conditioning and counter-guessing rule
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.
Mortal Kombat
Near-deterministic systems
Mortal Kombat leans a little harder on optimization, though the gap is small.
Fatal Fury Special
Punish routes and plane-shift tactics are learnable.
Mortal Kombat
Frame data and matchup study converge to known answers
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.
