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

Execution · Pure Mechanics
A classic co-op beat-em-up fantasy brawler focused on combat execution.

Execution · Practiced Mastery
An endless runner testing reaction timing across Spider-Man multiverse stages.
Golden Axe II leans Execution (Pure Mechanics); Marvel Spider-Man Unlimited 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.
Golden Axe II
melee combo and dodge timing vs enemies
Marvel Spider-Man Unlimited
Reaction timing on swiping and dodging carries runs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Golden Axe II
enemies run fixed scripted attack patterns
Marvel Spider-Man Unlimited
Endless runner, no opponent to model
Marvel Spider-Man Unlimited leans a little harder on variance, though the gap is small.
Golden Axe II
magic potion and enemy spawn randomness
Marvel Spider-Man Unlimited
Randomized obstacle spawns add some chaos
Marvel Spider-Man Unlimited leans a little harder on optimization, though the gap is small.
Golden Axe II
character and beast-mount choice optimization
Marvel Spider-Man Unlimited
Character collection and upgrades improve scores
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.
