head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Modern-military shooting execution with a light multiplayer prediction layer.

Execution · Pure Mechanics
Arcade soccer testing reflex tackles and super-shot timing.
Medal of Honor leans Execution (Pure Mechanics); Nintendo World Cup leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor
Aimbot trivialises both scripted campaign and multiplayer firefights
Nintendo World Cup
Tackles and super-shot timing decide most goals
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor
Human multiplayer lobbies add modest prediction
Nintendo World Cup
Versus a human, shot fakes add light 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
Scripted ambushes are unknown only on first contact
Nintendo World Cup
Ball physics add minor chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor
Map and loadout knowledge add a light planning layer
Nintendo World Cup
Learning super-move triggers is a small solvable layer
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.
