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

Execution · Practiced Mastery
Reversal-timing execution with human habit-reading layered over wrestling systems.

Execution · Competitive PvP
Reversal-timing duels where humans bait each other inside scripted spectacle.
WWE 2K23 leans Execution (Practiced Mastery); WWE SmackDown vs. Raw 2011 leans Execution (Competitive PvP).
WWE 2K23 leans a little harder on execution, though the gap is small.
WWE 2K23
Reversal timing windows and combo strings decide matches
WWE SmackDown vs. Raw 2011
Reversal timing windows reward practiced reactions
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
WWE 2K23
Human opponents reward baiting predictable reversal habits
WWE SmackDown vs. Raw 2011
Versus humans, reversal baiting becomes a guessing duel
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
WWE 2K23
Match stipulations and AI logic add mild chaos
WWE SmackDown vs. Raw 2011
Momentum swings and AI quirks add mild chaos
WWE 2K23 leans a little harder on optimization, though the gap is small.
WWE 2K23
Move-set knowledge, stamina and meta builds are studyable
WWE SmackDown vs. Raw 2011
Move sets, match types and creation systems are learnable
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.
