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

Execution · Practiced Mastery
Tests sustained crowd-kiting and spawner-priority decisions in co-op dungeon runs.

Execution · Practiced Mastery
Two Spider-Men, faster traversal, and deeper combo systems.
Gauntlet Legends leans Execution (Practiced Mastery); Marvel's Spider-Man 2 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.
Gauntlet Legends
Kiting endless spawners while shooting is the moment-to-moment test
Marvel's Spider-Man 2
Symbiote and dual-hero combat demands inputs.
Marvel's Spider-Man 2 leans a little harder on reads, though the gap is small.
Gauntlet Legends
Mobs pour from generators on fixed logic
Marvel's Spider-Man 2
Enemies scripted, not modeling player.
Gauntlet Legends leans a little harder on variance, though the gap is small.
Gauntlet Legends
Item and food spots are scripted-but-unknown initially
Marvel's Spider-Man 2
Light open-world randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gauntlet Legends
Generator-killing priority and character leveling reward planning
Marvel's Spider-Man 2
Expanded skill trees and gadget combos solvable.
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.
