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.

Optimization · Practiced Mastery
Series finale blending stealth with active battlefields and heavy cinematics.

Optimization · Practiced Mastery
FPS scenarios converted into solvable sequencing puzzles by stopped time.
Metal Gear Solid 4: Guns of the Patriots leans Optimization (Practiced Mastery); SuperHot 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 4: Guns of the Patriots
flexible gunplay alongside sneaking
SuperHot
Time-stops-when-you-stop removes most twitch 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 4: Guns of the Patriots
battlefield factions act on scripts
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 4: Guns of the Patriots
mid-battle chaos mostly cosmetic
SuperHot
Spawn order is unknown on a first attempt only
SuperHot leans a little harder on optimization, though the gap is small.
Metal Gear Solid 4: Guns of the Patriots
camo, gear, and route knowledge per act
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.
