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
The free fan-made Guitar Hero engine where competitive charting and scoring live on.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Clone Hero leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Clone Hero leans a little harder on execution, though the gap is small.
Clone Hero
Community charts push fretting speed past official games
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Clone Hero
Charts are static
Super Mario Odyssey
No adaptive opponents whatsoever.
Super Mario Odyssey leans a little harder on variance, though the gap is small.
Clone Hero
Fully deterministic
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans a little harder on optimization, though the gap is small.
Clone Hero
Star power path calculation is a science
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.
