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

Execution · Pure Mechanics
Linear military FPS about resisting an occupation of the United States.

Execution · Pure Mechanics
An early top-down shootout game testing precise aim against a human opponent.
Homefront leans Execution (Pure Mechanics); Outlaw leans Execution (Pure Mechanics).
Outlaw leans a little harder on execution, though the gap is small.
Homefront
Standard shooter gunplay carries the campaign
Outlaw
precise aiming and movement in duels
Outlaw leans a little harder on reads, though the gap is small.
Homefront
Multiplayer adds some human prediction
Outlaw
human opponents adapt dueling tactics
Homefront leans a little harder on variance, though the gap is small.
Homefront
Scripted setpieces, little randomness
Outlaw
minimal randomness in shootouts
Homefront leans a little harder on optimization, though the gap is small.
Homefront
Modest loadout and map knowledge layer
Outlaw
minimal system depth
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.
