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 · Practiced Mastery
Careful climbing execution and route planning where a single mistimed grab undoes everything.

Execution · Pure Mechanics
Player-made platforming gauntlets where precision execution meets unseen level design.
Peak leans Execution (Practiced Mastery); Super Mario Maker leans Execution (Pure Mechanics).
Super Mario Maker leans a little harder on execution, though the gap is small.
Peak
Stamina-managed grip timing - one slipped input drops the whole climb
Super Mario Maker
Community kaizo levels push platforming precision to extremes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Peak
Co-op against a mountain, no adaptive opponent
Super Mario Maker
Levels are static once built; nothing adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Peak
Daily map rotation and item spawns shuffle each ascent
Super Mario Maker
Unknown user levels are hidden information until attempted
Peak leans a little harder on optimization, though the gap is small.
Peak
Routing the wall and rationing items decides summit attempts
Super Mario Maker
Mastering tool tech and level conventions is 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.
