head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, 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
Brawler combo execution against scripted bosses with light build tuning.
Marvel's Spider-Man leans Execution (Practiced Mastery); Teenage Mutant Ninja Turtles: Mutants in Manhattan leans Execution (Practiced Mastery).
Teenage Mutant Ninja Turtles: Mutants in Manhattan leans a little harder on execution, though the gap is small.
Marvel's Spider-Man
swinging flow and combat dodge timing
Teenage Mutant Ninja Turtles: Mutants in Manhattan
Combo timing, dodges and turtle-swaps carry the combat
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
Teenage Mutant Ninja Turtles: Mutants in Manhattan
Bosses telegraph scripted patterns, nothing adapts
Teenage Mutant Ninja Turtles: Mutants in Manhattan leans a little harder on variance, though the gap is small.
Marvel's Spider-Man
open world is fully discoverable
Teenage Mutant Ninja Turtles: Mutants in Manhattan
Mission modifiers shuffle encounters mildly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel's Spider-Man
gadget loadouts and suit mods are shallow but present
Teenage Mutant Ninja Turtles: Mutants in Manhattan
Charm builds and combo knowledge raise rank ceilings
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.
