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 · Grand Arena
A hero shooter where teams brawl over objectives using locked ability kits.

Execution · Grand Arena
A tactical hero shooter decided by aim duels and adapting to human opponents.
Overwatch 2 leans Execution (Grand Arena); Valorant leans Execution (Grand Arena).
Valorant leans a little harder on execution, though the gap is small.
Overwatch 2
Aim and ability timing decide most duels.
Valorant
One-tap aim and crosshair placement decide most duels.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Overwatch 2
Adaptive enemy comp counters and ult baiting.
Valorant
Humans constantly adapt peeks, fakes, and ability timings.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Overwatch 2
Minimal randomness, mostly map and matchmaking.
Valorant
Light spray RNG and unknown enemy positions.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Overwatch 2
Comp building, ult economy, and cooldown tracking.
Valorant
Agent comps, util usage, and economy are studyable theory.
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.
