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

Execution · Pure Mechanics
Routine shooter aim through scripted cartel firefights.

Execution · Pure Mechanics
Modern-military shooting execution with a light multiplayer prediction layer.
Call of Juarez: The Cartel leans Execution (Pure Mechanics); Medal of Honor 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.
Call of Juarez: The Cartel
Standard FPS gunfights run on aim alone
Medal of Honor
Aimbot trivialises both scripted campaign and multiplayer firefights
Medal of Honor leans a little harder on reads, though the gap is small.
Call of Juarez: The Cartel
Co-op secret objectives add mild teammate suspicion
Medal of Honor
Human multiplayer lobbies add modest prediction
Medal of Honor leans a little harder on variance, though the gap is small.
Call of Juarez: The Cartel
Enemy waves spawn identically each run
Medal of Honor
Scripted ambushes are unknown only on first contact
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Juarez: The Cartel
Weapon levelling is a thin progression layer
Medal of Honor
Map and loadout knowledge add a light planning 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.
