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

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

Assassin's Creed III: Liberation leans a little harder on variance, though the gap is small.
Assassin's Creed III: Liberation
Light patrol and notoriety randomness
Overlord

Overlord
Minion type usage and upgrade economy reward planning
