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
The battle royale archetype: loot, rotate, and outlast 99 opponents inside a shrinking circle.

Execution · Grand Arena
An early battle royale shooter where dozens of players loot, drive, and shoot to be the last one standing.
PlayerUnknown's Battlegrounds leans Execution (Grand Arena); Z1 Battle Royale 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.
PlayerUnknown's Battlegrounds
Recoil control and long-range ballistics
Z1 Battle Royale
Gunplay, bullet drop, and car control under pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
PlayerUnknown's Battlegrounds
99 humans rotating and ambushing adaptively
Z1 Battle Royale
Human opponents rotate, bait, and adapt to you
PlayerUnknown's Battlegrounds leans a little harder on variance, though the gap is small.
PlayerUnknown's Battlegrounds
Loot spawns and circle placement shape every match
Z1 Battle Royale
Loot spawns, drop locations, and gas circles
PlayerUnknown's Battlegrounds leans a little harder on optimization, though the gap is small.
PlayerUnknown's Battlegrounds
Zone rotations and positioning theory are learnable
Z1 Battle Royale
Loadout and rotation strategy is a thinner 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.
