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

Execution · Pure Mechanics
Punishing combat execution against fast scripted enemies with deep encounter solutions.

Execution · Practiced Mastery
Drilling fixed enemy movesets until parry-perfect execution carries a run.
Ninja Gaiden II Black leans Execution (Pure Mechanics); Sifu leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Ninja Gaiden II Black
Frame-tight blocking, dodging and combo routing define survival
Sifu
Parry and dodge timing on tight windows is everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ninja Gaiden II Black
Aggressive enemies still run scripted, learnable behaviour
Sifu
Enemies attack from fixed movesets, never adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ninja Gaiden II Black
Encounters fixed; spawns known after one run
Sifu
Levels are deterministic once learned
Sifu leans a little harder on optimization, though the gap is small.
Ninja Gaiden II Black
Weapon choice, essence economy and encounter solutions matter
Sifu
Learning movesets, shortcuts and the aging economy is the meta
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.
