Portal leans clearly harder on execution.
Omori
Turn-based menus, no dexterity needed
Portal
Portal placement timing modest.

Portal
No adversary modeling player.
Variance2 vs 0
Omori leans clearly harder on variance.
Omori

Omori
Emotion triangle and follow-ups are easily solvable
Portal
Pure puzzle-solving optimization.
