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.

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

Optimization · Practiced Mastery
FPS scenarios converted into solvable sequencing puzzles by stopped time.
Metal Gear Solid 2: Sons of Liberty leans Optimization (Practiced Mastery); SuperHot leans Optimization (Practiced Mastery).
Metal Gear Solid 2: Sons of Liberty leans a little harder on execution, though the gap is small.
Metal Gear Solid 2: Sons of Liberty
First-person aim and guard reaction windows demand precise input
SuperHot
Time-stops-when-you-stop removes most twitch pressure
Metal Gear Solid 2: Sons of Liberty leans a little harder on reads, though the gap is small.
Metal Gear Solid 2: Sons of Liberty
Guards radio for backup on scripted triggers, not adaptive tactics
SuperHot
Red guys follow spawn scripts, not minds
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
SuperHot
Spawn order is unknown on a first attempt only
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
SuperHot
Each level is a solvable movement-and-kill-order puzzle
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.
