head to head

Kingdom Hearts II leans clearly harder on execution.
Kingdom Hearts II
Revenge values and Data fights demand precise play
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.

Kingdom Hearts II
Even superbosses run scripted, mappable patterns
Red Dead Redemption 2

Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Kingdom Hearts II
Fully visible action systems
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.

Kingdom Hearts II
Forms, abilities, and boss study reward labbing
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
