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

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
Deadline-driven strategy where three explorers split duties harvesting fruit with Pikmin squads.

Fallout: New Vegas leans a little harder on reads, though the gap is small.

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
