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 · Practiced Mastery
Luchador metroidvania mixing brawler combos with demanding color-switch platforming.

Execution · Pure Mechanics
Pure jump timing over fully fixed, memorisable levels.
Guacamelee! leans Execution (Practiced Mastery); Super Mario Bros. leans Execution (Pure Mechanics).
Super Mario Bros. leans a little harder on execution, though the gap is small.
Guacamelee!
Combo brawling and dimension-swap platforming challenges
Super Mario Bros.
Perfect inputs trivialise momentum jumps over fixed hazards
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Guacamelee!
Enemies telegraph fixed patterns
Super Mario Bros.
Goombas walk left forever - nothing to predict
Guacamelee! leans a little harder on variance, though the gap is small.
Guacamelee!
Authored world with no randomness
Super Mario Bros.
Every level is identical on every run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Guacamelee!
Ability routing, combos, and secret hunting
Super Mario Bros.
Level memorisation and warp routing are fully solvable
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.
