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.

Optimization · Systems & Chaos
A paranoid sci-fi thriller where choosing between positive and negative delusions shapes which reality the protagonist inhabits.

Optimization · Pure Optimization
A psychological horror RPG where a shut-in's dream world slowly cracks around a buried truth.
Chaos;Head leans Optimization (Systems & Chaos); Omori leans Optimization (Pure Optimization).
Omori leans a little harder on execution, though the gap is small.
Chaos;Head
Reading only; delusion trigger choices are the input
Omori
Turn-based menus, no dexterity needed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Chaos;Head
Conspiracies are scripted; no adaptive opponent
Omori
Scripted encounters throughout
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Chaos;Head
Delusion trigger system hides which mental responses lead to each route
Omori
Minor drop and emotion randomness
Omori leans a little harder on optimization, though the gap is small.
Chaos;Head
Choosing the correct delusion triggers per scene to reach the true end
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.
