head to head
Grand Theft Auto V asks more than Cooking Simulator, and the gap is reads.

Execution · Practiced Mastery
Managing kitchen workflow through deliberately fiddly physics-based food handling.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Cooking Simulator leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Cooking Simulator leans a little harder on execution, though the gap is small.
Cooking Simulator
Physics-based chopping and plating punishes clumsy hands
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans clearly harder on reads.
Cooking Simulator
Orders arrive from a queue, not a mind
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cooking Simulator
Order flow randomizes mildly per shift
Grand Theft Auto V
Some mission and lobby randomness.
Cooking Simulator leans a little harder on optimization, though the gap is small.
Cooking Simulator
Kitchen workflow and recipe routines are learnable systems
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
