head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Execution · Practiced Mastery
The black-sheep sequel whose passive enemies and dominant guns sand the series' skill ceiling way down.

Execution · Practiced Mastery
A cel-shaded open-city adventure where you play both Spider-Man and Venom.
Devil May Cry 2 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.
Devil May Cry 2
Infamously easy; guns trivialize most encounters
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.
Devil May Cry 2
Passive enemy AI never pressures, let alone adapts
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.
Devil May Cry 2
Flat authored levels hide little
Ultimate Spider-Man
Fixed open city with set events
Devil May Cry 2 leans a little harder on optimization, though the gap is small.
Devil May Cry 2
Amulet builds and boss patterns fall fast
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.
