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

Neighbours from Hell 2: On Vacation leans a little harder on reads, though the gap is small.

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell 2: On Vacation
some randomness in reaction timing
Omori
Minor drop and emotion randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

puzzle-solving trap sequences per room
Omori
Emotion triangle and follow-ups are easily solvable
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.
