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
Arcade run-and-gun reflexes against fully memorisable boss patterns.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Sunset Riders leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Sunset Riders leans a little harder on execution, though the gap is small.
Sunset Riders
Dodging bullet spreads and snap-shooting bosses is everything
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.
Sunset Riders
Bandits and bosses cycle memorisable arcade patterns
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.
Sunset Riders
Spawns are deterministic each credit
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sunset Riders
Pattern memorisation for one-credit clears is the meta-game
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.
