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 combat metroidvania testing precise platforming execution against fixed enemy patterns.

Execution · Pure Mechanics
A classic 2D Mario platformer rewarding tight jump execution above all.
Guacamelee! Super Turbo Championship Edition leans Execution (Pure Mechanics); New Super Mario Bros. U Deluxe leans Execution (Pure Mechanics).
New Super Mario Bros. U Deluxe leans a little harder on execution, though the gap is small.
Guacamelee! Super Turbo Championship Edition
Combo brawling and dimension-swap platforming demand tight inputs
New Super Mario Bros. U Deluxe
precise jump and platforming execution
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Guacamelee! Super Turbo Championship Edition
Enemies and bosses are colour-coded fixed patterns
New Super Mario Bros. U Deluxe
fixed enemy patterns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Guacamelee! Super Turbo Championship Edition
Hand-built world with nothing random
New Super Mario Bros. U Deluxe
minor enemy placement randomness
Guacamelee! Super Turbo Championship Edition leans a little harder on optimization, though the gap is small.
Guacamelee! Super Turbo Championship Edition
Ability-gated routing and upgrade order reward planning
New Super Mario Bros. U Deluxe
level routing for speed/collectibles
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.
