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 · Pure Mechanics
An arcade rail-shooter testing raw reflexes in fast jet combat.

Execution · Pure Mechanics
A classic beat-em-up demanding execution against scripted enemy waves.
After Burner II leans Execution (Pure Mechanics); Teenage Mutant Ninja Turtles III: The Manhattan Project leans Execution (Pure Mechanics).
After Burner II leans a little harder on execution, though the gap is small.
After Burner II
reflex-heavy dodging and shooting
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.
After Burner II
scripted enemy waves, not adaptive
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.
After Burner II
minimal randomness in enemy patterns
Teenage Mutant Ninja Turtles III: The Manhattan Project
minor enemy spawn randomness
Teenage Mutant Ninja Turtles III: The Manhattan Project leans a little harder on optimization, though the gap is small.
After Burner II
little systemic depth beyond memorization
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.
