head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
An arcade test of jump timing and enemy-flipping precision on a single screen.

Execution · Pure Mechanics
A top-down action shooter testing aim and cover timing in noir gunfights.
Mario Bros. leans Execution (Pure Mechanics); Milanoir 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.
Mario Bros.
Precise jumps and bump timing under crowding enemies decide survival
Milanoir
Twin-stick aiming and cover timing drive firefights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Bros.
Versus mode adds light human interference, enemies are scripted
Milanoir
Enemies follow scripts, no adaptive prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Bros.
Enemy spawns vary slightly but patterns are quickly learned
Milanoir
Enemy spawn timing adds minor chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Bros.
POW block usage and enemy routing have known best lines
Milanoir
Cover use and weapon choice reward planning
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.
