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
Gothic action platformer starring a one-eyed undead knight reclaiming his honor.

Execution · Practiced Mastery
A cel-shaded open-city adventure where you play both Spider-Man and Venom.
MediEvil leans Execution (Practiced Mastery); Ultimate Spider-Man 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.
MediEvil
stiff swordplay and platforming timing
Ultimate Spider-Man
Swinging momentum and boss chases reward control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
MediEvil
skeletons follow fixed patterns
Ultimate Spider-Man
Scripted villains and pedestrians
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
MediEvil
deterministic levels and secrets
Ultimate Spider-Man
Fixed open city with set events
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
MediEvil
chalice hunting and weapon progression routing
Ultimate Spider-Man
Race routes and combat upgrades are learnable
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.
