head to head
FIFA 22 asks more than Battlefield 4, and the gap is reads.

Execution · Competitive PvP
Combined-arms multiplayer shooter famous for map-altering levolution moments and 64-player conquest.

Execution · Competitive PvP
Outplaying a human opponent through input precision and constant tactical guessing.
Battlefield 4 leans Execution (Competitive PvP); FIFA 22 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield 4
Gunplay, vehicle mastery, and movement under fire
FIFA 22
Perfect inputs win skill moves, timed finishing and defending
FIFA 22 leans clearly harder on reads.
Battlefield 4
Human teams adapt to flanks and levolution chokes
FIFA 22
Outguessing a human's passing and defensive habits is the edge
FIFA 22 leans a little harder on variance, though the gap is small.
Battlefield 4
Map-altering events and spawns inject noise
FIFA 22
Deflections, ref calls and pack luck inject real randomness
Battlefield 4 leans a little harder on optimization, though the gap is small.
Battlefield 4
Loadout tuning and objective rotation knowledge
FIFA 22
Formations, tactics and squad building sit underneath the duel
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.
