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
Multiverse-hopping action sequel adding controllable kaiju demons to the combo sandbox.

Execution · Practiced Mastery
A rhythm-driven character action game where everything moves to the beat.
Bayonetta 3 leans Execution (Pure Mechanics); Hi-Fi Rush leans Execution (Practiced Mastery).
Bayonetta 3 leans a little harder on execution, though the gap is small.
Bayonetta 3
Demon Slave juggling atop precise dodge play
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.
Bayonetta 3
Homunculi follow fixed attack scripts
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.
Bayonetta 3
Deterministic stages with light exploration drops
Hi-Fi Rush
Minimal randomness in encounters.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bayonetta 3
Demon and weapon synergies plus score routing
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.
