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

Execution · Competitive PvP
Stick execution and reading human opponents within a meta-driven system.

Execution · Competitive PvP
Shot-timing execution against adapting human defense, on top of build and playbook math.
FIFA 18 leans Execution (Competitive PvP); NBA 2K17 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.
FIFA 18
Perfect stick skill and timing dominate dribbles and finishing
NBA 2K17
Shot meter timing and dribble execution decide possessions
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 18
Human opponents bait, switch tactics and counter your habits
NBA 2K17
Online opponents adapt defensive schemes and bait plays
FIFA 18 leans a little harder on variance, though the gap is small.
FIFA 18
Bounce physics and pack luck add measured chaos
NBA 2K17
Shot RNG wraps the timing meter
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 18
Formation, squad chemistry and meta mechanics reward study
NBA 2K17
Build math, playbooks and matchup hunting underpin wins
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.
