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
The divisive middle Souls game, slower and stat-heavier than its siblings.

Execution · Practiced Mastery
The series' action peak, with flashy drive forms and superbosses that built a lasting challenge-run community.
Dark Souls II leans Execution (Practiced Mastery); Kingdom Hearts II leans Execution (Practiced Mastery).
Dark Souls II leans a little harder on execution, though the gap is small.
Dark Souls II
stamina and adaptability-gated dodge timing
Kingdom Hearts II
Revenge values and Data fights demand precise play
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls II
invasions add rare human mind games
Kingdom Hearts II
Even superbosses run scripted, mappable patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls II
fixed world, known after one trip
Kingdom Hearts II
Fully visible action systems
Dark Souls II leans a little harder on optimization, though the gap is small.
Dark Souls II
builds and boss patterns reward study
Kingdom Hearts II
Forms, abilities, and boss study reward labbing
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.
