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
Precise jump execution across fixed levels with secrets to memorise.

Execution · Pure Mechanics
Consistent precision driving through touring-car packs on learnable circuits.
Super Mario World leans Execution (Pure Mechanics); TOCA Championship Racing leans Execution (Pure Mechanics).
TOCA Championship Racing leans a little harder on execution, though the gap is small.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
TOCA Championship Racing
Consistent lap precision through traffic decides every championship
TOCA Championship Racing leans a little harder on reads, though the gap is small.
Super Mario World
Scripted Koopas adapt to nothing
TOCA Championship Racing
AI drivers follow fixed racing behaviour
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
TOCA Championship Racing
Pack collisions add mild chaos to race starts
TOCA Championship Racing leans a little harder on optimization, though the gap is small.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
TOCA Championship Racing
Track learning and racecraft lines reward systematic study
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.
