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
Execution on the ball plus constant prediction of the other player's shape.

Execution · Practiced Mastery
Reversal-timing execution with human habit-reading layered over wrestling systems.
Pro Evolution Soccer 2009 leans Execution (Competitive PvP); WWE 2K23 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Close control and finishing windows demand stick precision
WWE 2K23
Reversal timing windows and combo strings decide matches
Pro Evolution Soccer 2009 leans a little harder on reads, though the gap is small.
Pro Evolution Soccer 2009
Online and couch opponents adjust tactics against you
WWE 2K23
Human opponents reward baiting predictable reversal habits
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Pro Evolution Soccer 2009
Ricochets and keeper parries add small randomness
WWE 2K23
Match stipulations and AI logic add mild chaos
WWE 2K23 leans a little harder on optimization, though the gap is small.

Squad setup and tactical sliders reward preparation
WWE 2K23
Move-set knowledge, stamina and meta builds are studyable
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.
