head to head
Grand Theft Auto: San Andreas asks more than High on Life, 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
Comedy FPS where talking guns crack jokes through an alien bounty-hunting romp.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); High on Life leans Execution (Practiced Mastery).
High on Life leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
High on Life
Standard FPS aim and movement gadgets
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
High on Life
Bounty targets are scripted bosses
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
High on Life
Fixed encounters and levels
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
High on Life
Gun ability combos and exploration upgrades
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.
