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
A classic side-scrolling brawler focused on tight combat execution.

Execution · Practiced Mastery
Classic action execution through fixed levels and scripted boss patterns.
Final Fight 3 leans Execution (Pure Mechanics); Spider-Man leans Execution (Practiced Mastery).
Final Fight 3 leans a little harder on execution, though the gap is small.
Final Fight 3
beat-em-up combo and dodge execution
Spider-Man
Swinging, combat and timed escapes need real dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fight 3
enemies use fixed scripted aggression
Spider-Man
Villains repeat fixed boss patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fight 3
minor enemy spawn randomness
Spider-Man
Level events are scripted and quickly known
Spider-Man leans a little harder on optimization, though the gap is small.
Final Fight 3
character choice and combo-route optimization
Spider-Man
Boss patterns and level routes are fully learnable
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.
