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

Execution · Practiced Mastery
A near-future Call of Duty with squad-focused multiplayer and the Extinction mode.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Call of Duty: Ghosts leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Call of Duty: Ghosts leans clearly harder on execution.
Call of Duty: Ghosts
Fast time-to-kill rewards first-shot aim
Grand Theft Auto V
Driving and shooting demand decent inputs.
Call of Duty: Ghosts leans clearly harder on reads.
Call of Duty: Ghosts
Outguessing human routes and peeks matters
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Call of Duty: Ghosts leans a little harder on variance, though the gap is small.
Call of Duty: Ghosts
Spawns and lobby matchups add noise
Grand Theft Auto V
Some mission and lobby randomness.
Call of Duty: Ghosts leans a little harder on optimization, though the gap is small.
Call of Duty: Ghosts
Loadout and map knowledge are solvable layers
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.
