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
A PS4-era Killzone where a Shadow Marshal and his OWL drone fight through a divided Helghast city.

Execution · Competitive PvP
Family-friendly class shooter pitting plants against zombies across PvP and co-op.
Killzone Shadow Fall leans Execution (Pure Mechanics); Plants vs. Zombies: Garden Warfare 2 leans Execution (Competitive PvP).
Killzone Shadow Fall leans a little harder on execution, though the gap is small.
Killzone Shadow Fall
Standard FPS aim and movement ceiling
Plants vs. Zombies: Garden Warfare 2
Third-person shooting with forgiving hitboxes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Killzone Shadow Fall
PvP modes reward predicting human players
Plants vs. Zombies: Garden Warfare 2
Human opponents adapt in PvP modes
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Killzone Shadow Fall
Some open level routes and spawn noise
Plants vs. Zombies: Garden Warfare 2
Class ability rolls are minimal
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Killzone Shadow Fall
OWL drone usage and loadouts optimize cleanly
Plants vs. Zombies: Garden Warfare 2
Class counters and map knowledge help
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.
