head to head
Neither is simply harder - they are hard in different places. Grand Theft Auto: San Andreas demands more optimization; Toy Story Racer demands more execution.

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

Execution · Practiced Mastery
A kart racer testing cornering execution under item-driven chaos.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Toy Story Racer leans Execution (Practiced Mastery).
Toy Story Racer leans clearly harder on execution.

Flying school and drive-bys need decent hands
Toy Story Racer

Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Toy Story Racer
Track shortcuts and item usage reward learning
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.
