head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Competitive PvP
Cops-and-robbers spin on Battlefield built around heists, chases, and urban shootouts.

Execution · Competitive PvP
Mechanical football control plus predicting how a human opponent attacks.
Battlefield Hardline leans Execution (Competitive PvP); FIFA 16 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 Hardline
Close-quarters gunplay and high-speed vehicle chases
FIFA 16
Dribbling, defending and finishing inputs decide duels
FIFA 16 leans a little harder on reads, though the gap is small.
Battlefield Hardline
Cops-versus-criminals humans adapt heist tactics
FIFA 16
Human opponents online adapt tactics match to match
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield Hardline
Spawns and loot grabs shuffle engagements
FIFA 16
Deflections and finishing randomness swing close games
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield Hardline
Gadget loadouts and mode-specific route knowledge
FIFA 16
Formations and squad construction reward study
