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

Execution · Practiced Mastery
Dash-precision platforming with solvable boss orders and upgrade routing.

Execution · Practiced Mastery
GBA platformer where Wario smashes through puzzle levels and races escape timers for treasure.
Mega Man X5 leans Execution (Practiced Mastery); Wario Land 4 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X5
Dash-jump precision and boss dodge timing demand clean hands
Wario Land 4
Frantic escape sequences demand tight platforming under timers
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X5
Mavericks cycle fixed attack patterns
Wario Land 4
Fixed scripted levels with no adaptive opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X5
Random ending triggers add rare unmapped outcomes
Wario Land 4
Layouts fixed; only first-run secret discovery
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man X5
Armor parts, boss order and route knowledge solve the game
Wario Land 4
Treasure routing and frog-switch timing 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.
