head to head
Gears 5 asks more than Grand Theft Auto: San Andreas, and the gap is reads.

Execution · Practiced Mastery
A modern Gears entry spanning campaign, Horde, Escape, and ranked versus.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Gears 5 leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Gears 5 leans clearly harder on execution.
Gears 5
Movement tech and shotgun duels remain the core test
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Gears 5 leans clearly harder on reads.
Gears 5
Ranked versus rewards out-thinking human opponents
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.
Gears 5
Escape and Horde inject some run variance
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.
Gears 5
Character ultimates and map control are learnable
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.
