head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, 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 casual team shootout where aim and basic opponent awareness decide rounds.
Medal of Honor: Warfighter leans Execution (Competitive PvP); The Mean Greens: Plastic Warfare 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
The Mean Greens: Plastic Warfare
Aimbot would dominate these third-person toy-soldier shootouts
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
The Mean Greens: Plastic Warfare
Human opponents in objective modes reward positional prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Warfighter
Spawns and engagements add modest unpredictability
The Mean Greens: Plastic Warfare
Random spawns and chaotic lobbies add mild noise
Medal of Honor: Warfighter leans a little harder on optimization, though the gap is small.
Medal of Honor: Warfighter
Class loadouts and map knowledge form a thin layer
The Mean Greens: Plastic Warfare
Objective routes are simple; little system depth to solve
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.
