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.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Super Mario Odyssey leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Super Mario Odyssey leans a little harder on execution, though the gap is small.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
No adaptive opponents whatsoever.
Super Mario World
Scripted Koopas adapt to nothing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Almost no randomness in level design.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Super Mario Odyssey
Moon routes and movement tech learnable.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
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.
