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

Execution · Grand Arena
An extraction shooter where scavengers dodge killer machines and rival squads for loot.

Execution · Grand Arena
The battle royale archetype: loot, rotate, and outlast 99 opponents inside a shrinking circle.
ARC Raiders leans Execution (Grand Arena); PlayerUnknown's Battlegrounds leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
ARC Raiders
Gunplay and movement under machine fire
PlayerUnknown's Battlegrounds
Recoil control and long-range ballistics
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ARC Raiders
Rival squads ambush, bait, and adapt
PlayerUnknown's Battlegrounds
99 humans rotating and ambushing adaptively
PlayerUnknown's Battlegrounds leans a little harder on variance, though the gap is small.
ARC Raiders
Loot spawns and unknown player positions
PlayerUnknown's Battlegrounds
Loot spawns and circle placement shape every match
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
ARC Raiders
Loadout economy and map knowledge compound
PlayerUnknown's Battlegrounds
Zone rotations and positioning theory are learnable
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.
