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

Execution · Pure Mechanics
A boss-rush action game that is nothing but execution tests against scripted duelists.

Execution · Practiced Mastery
A rhythm-driven character action game where everything moves to the beat.
Furi leans Execution (Pure Mechanics); Hi-Fi Rush leans Execution (Practiced Mastery).
Furi leans a little harder on execution, though the gap is small.
Furi
Parry timing, bullet dodging, and duel precision
Hi-Fi Rush
Rhythm-timed combos demand precise inputs.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Furi
Bosses are scripted patterns, however adversarial they feel
Hi-Fi Rush
Bosses are scripted, not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Furi
Fixed boss sequences
Hi-Fi Rush
Minimal randomness in encounters.
Hi-Fi Rush leans a little harder on optimization, though the gap is small.
Furi
Learning each boss's phases converges to mastery
Hi-Fi Rush
Combo routes and chip builds reward optimization.
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.
