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

Online football where stick control meets reading opponents.

Execution · Grand Arena
Basketball sim layering shot timing over PvP reads.
EA Sports FC 24 leans Execution (Competitive PvP); NBA 2K24 leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
EA Sports FC 24
Precise stick skills, timing, dribbling under pressure
NBA 2K24
Shot timing, dribble combos, defensive sliding
EA Sports FC 24 leans a little harder on reads, though the gap is small.
EA Sports FC 24
Online play vs adapting humans rewards prediction
NBA 2K24

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
EA Sports FC 24
Minor RNG in deflections and momentum swings
NBA 2K24

NBA 2K24
MyTeam builds, badges, MyCareer grinding
