head to head
Call of Duty: WWII asks more than Grand Theft Auto V, and the gap is execution.

Execution · Practiced Mastery
A back-to-basics WWII Call of Duty centered on grounded multiplayer gunfights.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Call of Duty: WWII leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Call of Duty: WWII leans clearly harder on execution.
Call of Duty: WWII
Boots-on-ground gunskill decides most fights
Grand Theft Auto V

Call of Duty: WWII leans clearly harder on reads.
Call of Duty: WWII
Predicting enemy pushes on lanes matters
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Call of Duty: WWII leans a little harder on variance, though the gap is small.
Call of Duty: WWII
Spawns and loot crates inject randomness
Grand Theft Auto V
Some mission and lobby randomness.
Call of Duty: WWII leans a little harder on optimization, though the gap is small.
Call of Duty: WWII
Division builds and map lanes are learnable
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.
