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

Execution · Practiced Mastery
Movie tie-in action game following Niobe and Ghost through bullet-time brawls and chases.

Execution · Practiced Mastery
A WWII shooter taking a Marine through the Pacific island campaign.
Enter the Matrix leans Execution (Practiced Mastery); Medal of Honor: Pacific Assault leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Enter the Matrix
Bullet-time gunplay and kung-fu combos
Medal of Honor: Pacific Assault
Recoil-heavy gunplay in jungle firefights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Enter the Matrix
Agents and SWAT run fixed scripts
Medal of Honor: Pacific Assault
Squad and enemy AI follow scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Enter the Matrix
Encounter placement unknown first run
Medal of Honor: Pacific Assault
Jungle ambushes surprise only first time
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Enter the Matrix
Focus meter management and learned level layouts
Medal of Honor: Pacific Assault
Health-medic economy and routes are learnable
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.
