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 · Competitive PvP
Online football where stick control meets reading opponents.
Execution · Grand Arena
A hero shooter where teams brawl over objectives using locked ability kits.
EA Sports FC 24 leans Execution (Competitive PvP); Overwatch 2 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.
EA Sports FC 24
Precise stick skills, timing, dribbling under pressure
Overwatch 2
Aim and ability timing decide most duels.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
EA Sports FC 24
Online play vs adapting humans rewards prediction
Overwatch 2
Adaptive enemy comp counters and ult baiting.
EA Sports FC 24 leans a little harder on variance, though the gap is small.
EA Sports FC 24
Minor RNG in deflections and momentum swings
Overwatch 2

Overwatch 2
Comp building, ult economy, and cooldown tracking.
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.
