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
Open-world superhero game whose joy is fluid web-swinging and rhythmic combat.

Execution · Practiced Mastery
Visceral hack-and-slash movie tie-in where Wolverine shreds everything in reach.
Marvel's Spider-Man leans Execution (Practiced Mastery); X-Men Origins: Wolverine 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.
Marvel's Spider-Man
swinging flow and combat dodge timing
X-Men Origins: Wolverine
Lunge timing and combo flow carry brawls.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel's Spider-Man
thugs and bosses follow fixed patterns
X-Men Origins: Wolverine
Enemies attack on fixed scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel's Spider-Man
open world is fully discoverable
X-Men Origins: Wolverine
Almost none; encounters are staged.
X-Men Origins: Wolverine leans a little harder on optimization, though the gap is small.
Marvel's Spider-Man
gadget loadouts and suit mods are shallow but present
X-Men Origins: Wolverine
Mutagen builds and skill unlocks are simple to solve.
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.
