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

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 17
Dribbling, shooting and defending inputs decide individual duels
FIFA 17 leans a little harder on reads, though the gap is small.
Battlefield Hardline
Cops-versus-criminals humans adapt heist tactics
FIFA 17
Human opponents online keep shifting attacking and defending habits
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 17
Bounces, deflections and finishing RNG swing tight matches
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Gadget loadouts and mode-specific route knowledge
FIFA 17
Squad chemistry, formations and meta mechanics are studied layers
