head to head
Neither is simply harder - they are hard in different places. Grand Theft Auto V demands more reads; Prison Break: The Conspiracy demands more optimization.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Optimization · Practiced Mastery
Memorising guard patrol windows to route through a fixed prison.
Grand Theft Auto V leans Execution (Practiced Mastery); Prison Break: The Conspiracy leans Optimization (Practiced Mastery).
Grand Theft Auto V leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Prison Break: The Conspiracy
Stealth timing and minigame inputs are forgiving
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Prison Break: The Conspiracy
Guards patrol fixed deterministic routes
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Prison Break: The Conspiracy
Routines are unknown only until observed
Prison Break: The Conspiracy leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Prison Break: The Conspiracy
Memorising patrol windows and routes solves each mission
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.
