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

Optimization · Practiced Mastery
Threading precise inputs through scripted guard gauntlets aboard a controlled and memorisable facility.

Optimization · Practiced Mastery
Resource optimisation and scripted boss mastery carried by strong atmosphere and pacing.
Metal Gear Solid 2: Sons of Liberty leans Optimization (Practiced Mastery); Resident Evil Village leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 2: Sons of Liberty
First-person aim and guard reaction windows demand precise input
Resident Evil Village
Accurate aiming and ammo discipline under varied enemy pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 2: Sons of Liberty
Guards radio for backup on scripted triggers, not adaptive tactics
Resident Evil Village
Enemies and boss phases are scripted, no adaptive modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 2: Sons of Liberty
Alert timers and item pickups create some hidden-state tension
Resident Evil Village
Minor crafting-drop variance; encounters are mostly fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 2: Sons of Liberty
Chokepoint memorisation and radar manipulation are learnable and repeatable
Resident Evil Village
Merchant economy, weapon upgrades and area sequencing are solvable
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.
