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
One-thumb tap-timing precision over fixed courses with solvable coin routes.

Execution · Pure Mechanics
A classic beat-em-up demanding execution against scripted enemy waves.
Super Mario Run leans Execution (Practiced Mastery); Teenage Mutant Ninja Turtles III: The Manhattan Project leans Execution (Pure Mechanics).
Teenage Mutant Ninja Turtles III: The Manhattan Project leans a little harder on execution, though the gap is small.
Super Mario Run
One-handed tap timing for coin lines demands precision
Teenage Mutant Ninja Turtles III: The Manhattan Project
beat-em-up timing and enemy juggling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Run
Auto-runner with no adaptive opponent; Toad Rally is asynchronous
Teenage Mutant Ninja Turtles III: The Manhattan Project
enemies run simple fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Run
Courses are fixed and fully learnable
Teenage Mutant Ninja Turtles III: The Manhattan Project
minor enemy spawn randomness
Super Mario Run leans a little harder on optimization, though the gap is small.
Super Mario Run
Routing perfect coin runs is a solvable layout puzzle
Teenage Mutant Ninja Turtles III: The Manhattan Project
character choice and route memorization
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.
