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 · Pure Mechanics
An aerial arena shooter testing twitch piloting and prediction of human dogfighters.
Killzone Shadow Fall leans Execution (Pure Mechanics); Strike Vector EX leans Execution (Pure Mechanics).
Strike Vector EX leans a little harder on execution, though the gap is small.
Killzone Shadow Fall
Standard FPS aim and movement ceiling
Strike Vector EX
High-speed vector-switching dogfights demand precise aim and control
Strike Vector EX leans a little harder on reads, though the gap is small.
Killzone Shadow Fall
PvP modes reward predicting human players
Strike Vector EX
Predicting human pilots' transform timing wins duels
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
Strike Vector EX
Spawns and pickups add minor noise
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
Strike Vector EX
Loadout counters and map knowledge sit underneath
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.
