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 · Competitive PvP
A shallow novelty wrestler testing little beyond basic timing and weapon grabs.

Execution · Pure Mechanics
Linear military FPS about resisting an occupation of the United States.
Celebrity Deathmatch leans Execution (Competitive PvP); Homefront leans Execution (Pure Mechanics).
Homefront leans a little harder on execution, though the gap is small.
Celebrity Deathmatch
Button timing wins matches but the ceiling is low
Homefront
Standard shooter gunplay carries the campaign
Celebrity Deathmatch leans a little harder on reads, though the gap is small.
Celebrity Deathmatch
A couch opponent can be conditioned, shallowly
Homefront
Multiplayer adds some human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Celebrity Deathmatch
Random weapon drops shake up the ring
Homefront
Scripted setpieces, little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Celebrity Deathmatch
Learning each celebrity's finisher exhausts the depth fast
Homefront
Modest loadout and map knowledge 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.
