Omori leans a little harder on execution, though the gap is small.
MegaWorld
Menu-driven building with no physical demand
Omori
Turn-based menus, no dexterity needed

MegaWorld
Open-market trading against players adds light prediction
Omori

MegaWorld
Market swings carry some hidden information
Omori
Minor drop and emotion randomness
MegaWorld leans a little harder on optimization, though the gap is small.
MegaWorld
Resource chains and placement economics are the core test
Omori
Emotion triangle and follow-ups are easily solvable
