head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Competitive PvP
A military shooter testing aim with moderate prediction of human opponents online.

Execution · Competitive PvP
A soccer game testing passing timing and anticipation against opposing players.
Medal of Honor: Warfighter leans Execution (Competitive PvP); Ultimate Soccer leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Warfighter
Gunfights reward aim in both campaign and multiplayer
Ultimate Soccer
Passing and shot timing demand moderate control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Warfighter
Human opponents in multiplayer demand positional prediction
Ultimate Soccer
Versus humans, anticipating passes and runs matters
Ultimate Soccer leans a little harder on variance, though the gap is small.
Medal of Honor: Warfighter
Spawns and engagements add modest unpredictability
Ultimate Soccer
Deflections and keeper saves add chance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Warfighter
Class loadouts and map knowledge form a thin layer
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.
