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
Dodging scripted bullet waves while grinding an upgrade economy to brute-force medals.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Sky Force Anniversary leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Sky Force Anniversary leans a little harder on execution, though the gap is small.
Sky Force Anniversary
Weaving dense bullet patterns is the entire moment-to-moment test
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.
Sky Force Anniversary
Enemy waves follow fixed scripts every run
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.
Sky Force Anniversary
Spawns are deterministic; almost nothing to map
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Sky Force Anniversary leans a little harder on optimization, though the gap is small.
Sky Force Anniversary
Upgrade grinding and medal-route planning shape progression
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.
