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
Balletic side-scrolling shooter about chaining stylish slow-motion gun acrobatics.
Mega Man X5 leans Execution (Practiced Mastery); My Friend Pedro 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
My Friend Pedro
Slow-motion acrobatic gunplay rewards precise control
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
My Friend Pedro
Enemies are static placements
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
My Friend Pedro
Deterministic levels
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
My Friend Pedro
Score-chasing optimal routes and trick chains
