head to head
Fortnite asks more than FIFA 22, and the gap is optimization.

Execution · Competitive PvP
Outplaying a human opponent through input precision and constant tactical guessing.

Execution · Grand Arena
Build-fight battle royale with deep mechanics.
FIFA 22 leans Execution (Competitive PvP); Fortnite leans Execution (Grand Arena).
Fortnite leans a little harder on execution, though the gap is small.
FIFA 22
Perfect inputs win skill moves, timed finishing and defending
Fortnite
Build-edit-aim combos punish slow hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 22
Outguessing a human's passing and defensive habits is the edge
Fortnite
Box fights are pure adaptive mind games
Fortnite leans a little harder on variance, though the gap is small.
FIFA 22
Deflections, ref calls and pack luck inject real randomness
Fortnite
Loot drops, storm, item rotations vary
Fortnite leans clearly harder on optimization.
FIFA 22
Formations, tactics and squad building sit underneath the duel
Fortnite
Loadouts, mats economy, rotations solvable
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.
