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
Tense, linear Metroid hunted through a station by a clone of yourself.

Execution · Practiced Mastery
The PS1 third-person espionage shooter following agent Gabe Logan against a viral terror plot.
Metroid Fusion leans Execution (Practiced Mastery); Syphon Filter 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.
Metroid Fusion
demanding bosses for a 2D Metroid
Syphon Filter
Taser duels and headshots under pressure test the hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid Fusion
SA-X stalking runs on fixed scripts
Syphon Filter
Terrorist AI is scripted spawns and patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid Fusion
first-encounter dread fades once mapped
Syphon Filter
Minor first-run uncertainty in enemy placements
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid Fusion
guided structure still rewards route and pattern knowledge
Syphon Filter
Memorizing levels and weapon stashes makes runs routine
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.
