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
Balletic side-scrolling shooter about chaining stylish slow-motion gun acrobatics.

Execution · Practiced Mastery
Arthur's infamous SNES gauntlet of armor-shattering hazards that must be beaten twice with the right weapon.
My Friend Pedro leans Execution (Practiced Mastery); Super Ghouls 'n Ghosts leans Execution (Practiced Mastery).
Super Ghouls 'n Ghosts leans a little harder on execution, though the gap is small.
My Friend Pedro
Slow-motion acrobatic gunplay rewards precise control
Super Ghouls 'n Ghosts
Committed double jump and relentless hazards punish errors
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
My Friend Pedro
Enemies are static placements
Super Ghouls 'n Ghosts
Scripted spawns, no adaptation
Super Ghouls 'n Ghosts leans a little harder on variance, though the gap is small.
My Friend Pedro
Deterministic levels
Super Ghouls 'n Ghosts
Chest contents and zombie spawns add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
My Friend Pedro
Score-chasing optimal routes and trick chains
Super Ghouls 'n Ghosts
Weapon management and mandatory second loop demand routing
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.
