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

Shot timing and play selection against opponents adjusting to your tendencies.

Execution · Practiced Mastery
Reversal-timing execution with human habit-reading layered over wrestling systems.
NBA 2K14 leans Execution (Competitive PvP); WWE 2K23 leans Execution (Practiced Mastery).

NBA 2K14
Shot RNG sways close possessions
WWE 2K23
Match stipulations and AI logic add mild chaos

Playbook knowledge and roster management reward study
WWE 2K23
