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 · Competitive PvP
Mobile shooter execution with human prediction, plus loot variance in battle royale.

Execution · Pure Mechanics
Tactical SWAT shooter with lethal TTK.
Call of Duty: Mobile leans Execution (Competitive PvP); Ready or Not leans Execution (Pure Mechanics).
Ready or Not leans a little harder on execution, though the gap is small.
Call of Duty: Mobile
Touch or controller aim and movement decide gunfights
Ready or Not
Lethal TTK and recoil punish slop
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Mobile
Human lobbies adapt rotations and peeks each match
Ready or Not
Mostly scripted suspects, limited reads
Ready or Not leans a little harder on variance, though the gap is small.
Call of Duty: Mobile
Battle royale drops and loot add run-to-run randomness
Ready or Not
Suspect placement and AI behavior varies
Ready or Not leans a little harder on optimization, though the gap is small.
Call of Duty: Mobile
Loadout meta and map spawn knowledge reward study
Ready or Not
Loadouts, breaching tools, team plans
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.
