head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A twin-stick arcade shooter where flawless movement through layered projectile patterns and human-rescue routing is the skill ceiling.

Execution · Practiced Mastery
Arthur's infamous SNES gauntlet of armor-shattering hazards that must be beaten twice with the right weapon.
Nex Machina leans Execution (Practiced Mastery); Super Ghouls 'n Ghosts 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.
Nex Machina
Rapid dodging through layered lasers and bullets is the entire test
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.
Nex Machina
All enemy behaviour is scripted arcade-style
Super Ghouls 'n Ghosts
Scripted spawns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Nex Machina
Enemy arrangement has minor randomisation between waves
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.
Nex Machina
Human rescue routing and weapon pick sequencing reward study
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.
