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 snowboarding game testing trick execution and run routing for high scores.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Amped 3 leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Amped 3 leans a little harder on execution, though the gap is small.
Amped 3
Trick input timing and landing balance are the core test
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Amped 3 leans a little harder on reads, though the gap is small.
Amped 3
Solo riding with no adaptive opponent
Super Mario World
Scripted Koopas adapt to nothing
Amped 3 leans a little harder on variance, though the gap is small.
Amped 3
Fixed terrain; minor event variation
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Amped 3 leans a little harder on optimization, though the gap is small.
Amped 3
Line choice and trick chaining maximize scores
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.
