head to head
Grand Theft Auto V asks more than Sonic Runners Adventure, and the gap is reads.

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

Execution · Practiced Mastery
An endless runner starring Sonic and friends.
Grand Theft Auto V leans Execution (Practiced Mastery); Sonic Runners Adventure leans Execution (Practiced Mastery).
Sonic Runners Adventure leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Sonic Runners Adventure
precise timing jumps and dashes at speed
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Sonic Runners Adventure
no adaptive opponent, solo endless runner
Sonic Runners Adventure leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Sonic Runners Adventure
obstacle and item layouts randomized
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Heists, money loops, builds learnable.
Sonic Runners Adventure
character and item upgrade optimization
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.
