head to head
Call of Duty: Warzone asks more than Arena Breakout: Infinite, and the gap is execution.

Execution · Grand Arena
High-stakes extraction raids testing aim, opponent prediction, and loot-economy mastery at once.

Execution · Grand Arena
Battle royale built on COD's tight gunplay.
Arena Breakout: Infinite leans Execution (Grand Arena); Call of Duty: Warzone leans Execution (Grand Arena).
Call of Duty: Warzone leans clearly harder on execution.
Arena Breakout: Infinite
Gunfights against humans punish slow aim instantly
Call of Duty: Warzone
Long-range gunfights reward perfect aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Arena Breakout: Infinite
Predicting other squads' rotations and ambushes is constant
Call of Duty: Warzone
Rotations and third-party reads decide fights
Arena Breakout: Infinite leans a little harder on variance, though the gap is small.
Arena Breakout: Infinite
Loot spawns and unseen player positions dominate raid outcomes
Call of Duty: Warzone
Drops, loot, circles inject real RNG
Arena Breakout: Infinite leans a little harder on optimization, though the gap is small.
Arena Breakout: Infinite
Ammo tiers, insurance economy and map routes reward deep study
Call of Duty: Warzone
Meta loadouts and rotations heavily solved
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.
