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

Optimization · Practiced Mastery
Solving block-tower routes quickly enough to outrun the timer.

Optimization · Practiced Mastery
A portable Metal Gear pairing mission stealth with a base-building development metagame.
Catherine: Full Body leans Optimization (Practiced Mastery); Metal Gear Solid: Peace Walker 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.
Catherine: Full Body
Climbing fast under a rising floor demands quick precise inputs
Metal Gear Solid: Peace Walker
Boss vehicle fights and CQC chains test aim and timing.
Catherine: Full Body leans a little harder on reads, though the gap is small.
Catherine: Full Body
Versus modes against humans add a thin prediction layer
Metal Gear Solid: Peace Walker
Enemy AI is scripted and predictable.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Catherine: Full Body
Block layouts are fixed; little randomness once learned
Metal Gear Solid: Peace Walker
Missions are fixed; soldier recruitment adds slight randomness.
Metal Gear Solid: Peace Walker leans a little harder on optimization, though the gap is small.
Catherine: Full Body
Block-pushing techniques and route knowledge are the real ceiling
Metal Gear Solid: Peace Walker
Mother Base management and weapon development are pure systems.
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.
