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
Football sim testing execution and opponent reading under a studied tactical meta.

Reads · Mind & Math
A naval PvP shooter blending shell-lead aiming with reading human captains.
FIFA 21 leans Execution (Competitive PvP); World of Warships: Legends leans Reads (Mind & Math).
FIFA 21 leans a little harder on execution, though the gap is small.
FIFA 21
Skill moves and finishing mechanics demand practiced hands
World of Warships: Legends
Aiming shells with lead and timing matters in duels
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 21
Outguessing a human's defensive shape and attacking patterns is central
World of Warships: Legends
Predicting human captains' positioning and turns is central
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 21
Deflections, finishing RNG and pack luck colour outcomes
World of Warships: Legends
Shell dispersion and concealment add real chance
World of Warships: Legends leans a little harder on optimization, though the gap is small.
FIFA 21
Meta formations, custom tactics and squad building are studied deeply
World of Warships: Legends
Ship builds, angling, and map positioning are deep systems
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.
