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.

Execution · Practiced Mastery
Telekinetic third-person shooter with weird Bureau atmosphere.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Control leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Control leans a little harder on execution, though the gap is small.
Control
Service Weapon aim and dodge timing matter.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Control leans a little harder on reads, though the gap is small.
Control
Hiss enemies scripted, predictable.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Control
Mod drops and encounter spawns randomized.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Control
Mods, weapon forms, ability builds solvable.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
