head to head
Grand Theft Auto: San Andreas asks more than Ultimate Spider-Man, and the gap is optimization.

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

Execution · Practiced Mastery
A cel-shaded open-city adventure where you play both Spider-Man and Venom.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Ultimate Spider-Man leans Execution (Practiced Mastery).
Ultimate Spider-Man leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Ultimate Spider-Man
Swinging momentum and boss chases reward control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Ultimate Spider-Man
Scripted villains and pedestrians
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Ultimate Spider-Man
Fixed open city with set events
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Ultimate Spider-Man
Race routes and combat upgrades are learnable
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.
