head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Methodically dissecting intricate puzzle boxes whose mechanisms are fully solvable.

Optimization · Pure Optimization
A chibi Final Fantasy spin-off about capturing monsters and stacking them into totem teams.
The Room Three leans Optimization (Pure Optimization); World of Final Fantasy leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
The Room Three
Rotating and prodding mechanisms takes no dexterity
World of Final Fantasy
Turn-based stacking combat; no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Room Three
The Craftsman is narrative dressing, not an adaptive mind
World of Final Fantasy
Scripted bosses with fixed gimmicks
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Room Three
Hidden mechanisms are unknown until inspected, then fixed
World of Final Fantasy
Mirage capture conditions hidden until learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Room Three
Each puzzle box is a fully solvable mechanical system
World of Final Fantasy
Stack composition and mirage boards are a solvable system
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.
