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

Open-world superagent sandbox about leveling skills and hunting 500 agility orbs.

Optimization · Practiced Mastery
An action-command RPG where dodging and countering boss tells is half the battle.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
Aim, driving, and rooftop leaping
Mario & Luigi: Bowser's Inside Story
Every attack and dodge is a timed action command.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
Gangs are static spawn sets
Mario & Luigi: Bowser's Inside Story
Boss tells are fixed and learnable.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
Fixed world with placed collectibles
Mario & Luigi: Bowser's Inside Story
Little randomness beyond minor drops.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
