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
Forgiving spectacle combat that lightly tests combo execution.

Execution · Practiced Mastery
Brawler combo execution against scripted bosses with light build tuning.
Star Wars: The Force Unleashed II leans Execution (Pure Mechanics); Teenage Mutant Ninja Turtles: Mutants in Manhattan 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.
Star Wars: The Force Unleashed II
Combo timing and dodges carry the spectacle combat
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.
Star Wars: The Force Unleashed II
Stormtroopers follow simple fixed scripts
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.
Star Wars: The Force Unleashed II
Encounters are scripted and identical every run
Teenage Mutant Ninja Turtles: Mutants in Manhattan
Mission modifiers shuffle encounters mildly
Teenage Mutant Ninja Turtles: Mutants in Manhattan leans a little harder on optimization, though the gap is small.
Star Wars: The Force Unleashed II
Upgrade choices barely matter against forgiving difficulty
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.
