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
A claustrophobic first-person shooter horror game testing precise aim and stamina management under scarce resources.

Execution · Practiced Mastery
Open-world Stone Age action game about hunting and conquering tribal outposts with tamed beasts.
Cry of Fear leans Execution (Practiced Mastery); Far Cry Primal 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.
Cry of Fear
Fast-paced shooting with limited stamina and scarce ammo demands precision
Far Cry Primal
Bow aim, melee timing, beast control under pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cry of Fear
Enemies follow scripted assault patterns
Far Cry Primal
Scripted tribal AI never models the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cry of Fear
Some item locations are unknown on first run
Far Cry Primal
Wildlife encounters and patrol spawns are random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cry of Fear
Weapon selection, safe routing and stamina discipline are optimisable
Far Cry Primal
Outpost routes, crafting economy, beast taming order
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.
