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
Stylish character action where frame-perfect dodges slow time for absurd combo punishment.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Bayonetta leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Bayonetta leans a little harder on execution, though the gap is small.
Bayonetta
Witch Time dodges and long combo strings
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Bayonetta leans a little harder on reads, though the gap is small.
Bayonetta
Angels are scripted, never adaptive
Super Mario Odyssey
No adaptive opponents whatsoever.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bayonetta
Fixed encounters with minor enemy mix
Super Mario Odyssey
Almost no randomness in level design.
Bayonetta leans a little harder on optimization, though the gap is small.
Bayonetta
Combo routing and scoring for Pure Platinum
Super Mario Odyssey
Moon routes and movement tech learnable.
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.
