head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.

Execution · Pure Mechanics
Timing parkour inputs through fixed chase levels with escalating precision.
Super Mario World leans Execution (Pure Mechanics); Vector leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Vector
Precise swipe timing on parkour tricks decides every chase
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario World
Scripted Koopas adapt to nothing
Vector
The pursuing hunter is fully scripted
Super Mario World leans a little harder on variance, though the gap is small.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Vector
Levels are fixed with nothing random
Super Mario World leans a little harder on optimization, though the gap is small.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
Vector
Learning trick placements per level maximises scores
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.
