head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A fast solo FPS where managed aggression and weapon swapping sustain you.

Execution · Practiced Mastery
Drilling fixed enemy movesets until parry-perfect execution carries a run.
Doom Eternal leans Execution (Practiced Mastery); 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.
Doom Eternal
Weapon swapping and movement push the hands hard.
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.
Doom Eternal
Demon AI is scripted, not adaptive.
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.
Doom Eternal
Encounters are designed, not randomised.
Sifu
Levels are deterministic once learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Doom Eternal
Resource loops and weapon priority are solvable.
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.
