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
Player-made platforming gauntlets where precision execution meets unseen level design.

Execution · Pure Mechanics
A twin-stick arena blaster testing sustained dodging reflexes and upgrade picks.
Super Mario Maker leans Execution (Pure Mechanics); Ultratron 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.
Super Mario Maker
Community kaizo levels push platforming precision to extremes
Ultratron
Twin-stick dodging through bullet swarms is the entire test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Maker
Levels are static once built; nothing adapts
Ultratron
Robots swarm in fixed behaviours, nothing adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Maker
Unknown user levels are hidden information until attempted
Ultratron
Enemy spawns and power-up drops shuffle each level
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Maker
Mastering tool tech and level conventions is learnable
Ultratron
Upgrade pet-and-perk choices shape survivability
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.
