head to head
Neither is simply harder - they are hard in different places. Rhythm Heaven demands more execution; Super Mario World demands more optimization.

Execution · Pure Mechanics
Minimalist rhythm minigame collection demanding near-perfect beat timing.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Rhythm Heaven leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Rhythm Heaven leans clearly harder on execution.
Rhythm Heaven
Pure timing precision against audio cues.
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.
Rhythm Heaven
No opponent exists.
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.
Rhythm Heaven
Cue patterns are fixed once heard.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans clearly harder on optimization.
Rhythm Heaven
Learning each minigame's rhythm is shallow and quick.
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.
