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 · Practiced Mastery
A rhythm-driven character action game where everything moves to the beat.

Execution · Pure Mechanics
Course-corrected revision restoring difficulty to the trilogy's weakest entry.
Hi-Fi Rush leans Execution (Practiced Mastery); Ninja Gaiden 3: Razor's Edge leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Hi-Fi Rush
Rhythm-timed combos demand precise inputs.
Ninja Gaiden 3: Razor's Edge
Steel-on-bone counters still demand sharp hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hi-Fi Rush
Bosses are scripted, not adaptive.
Ninja Gaiden 3: Razor's Edge
Scripted enemy waves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hi-Fi Rush
Minimal randomness in encounters.
Ninja Gaiden 3: Razor's Edge
Deterministic encounters
Hi-Fi Rush leans a little harder on optimization, though the gap is small.
Hi-Fi Rush
Combo routes and chip builds reward optimization.
Ninja Gaiden 3: Razor's Edge
Simplified systems leave less to solve
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.
