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

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
A gleefully absurd open-world crime game where the Saints conquer Steelport as celebrity gangsters.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Saints Row: The Third leans Execution (Practiced Mastery).
Saints Row: The Third leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Saints Row: The Third
Generous shooting and driving keep the skill bar moderate
Saints Row: The Third leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Saints Row: The Third
Enemy syndicates never adapt to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Saints Row: The Third
Sandbox mayhem injects light randomness
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Saints Row: The Third
Upgrade trees and city-takeover income are straightforwardly maximised
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.
