head to head
Streets of Rage 3 asks more than Grand Theft Auto V, and the gap is execution.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
Crowd-control execution against memorised enemy waves in a classic belt-scroller.
Grand Theft Auto V leans Execution (Practiced Mastery); Streets of Rage 3 leans Execution (Practiced Mastery).
Streets of Rage 3 leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Streets of Rage 3
Perfect inputs trivialise crowd control, combos and weapon timing
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Streets of Rage 3
Co-op partner aside, enemies follow scripted aggression patterns
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Streets of Rage 3
Enemy waves are fixed once a route is learned
Streets of Rage 3 leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Streets of Rage 3
Routing enemy spawns and special-meter management is the depth layer
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.
