head to head
Call of Duty: Modern Warfare 2 asks more than Ultimate Soccer, and the gap is execution.

Execution · Competitive PvP
Blockbuster 2009 sequel famous for killstreak chains and frantic multiplayer.

Execution · Competitive PvP
A soccer game testing passing timing and anticipation against opposing players.
Call of Duty: Modern Warfare 2 leans Execution (Competitive PvP); Ultimate Soccer leans Execution (Competitive PvP).
Call of Duty: Modern Warfare 2 leans clearly harder on execution.
Call of Duty: Modern Warfare 2
Fast time-to-kill rewards raw aim and reflex
Ultimate Soccer
Passing and shot timing demand moderate control
Call of Duty: Modern Warfare 2 leans clearly harder on reads.
Call of Duty: Modern Warfare 2
Outguessing human rotations and flanks
Ultimate Soccer
Versus humans, anticipating passes and runs matters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Modern Warfare 2
Spawn flips and killstreak randomness
Ultimate Soccer
Deflections and keeper saves add chance
Call of Duty: Modern Warfare 2 leans clearly harder on optimization.
Call of Duty: Modern Warfare 2
Killstreak economy, loadout and map knowledge
Ultimate Soccer
Formation and passing-strategy choices carry light planning
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.
