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
Capcom's polished CPS2 vertical shooter built around a charging lock-on bomb and tight scoring play.

Execution · Pure Mechanics
Capcom's infamously punishing arcade platformer that makes you beat it twice for the real ending.
19XX: The War Against Destiny leans Execution (Practiced Mastery); Ghosts 'n Goblins leans Execution (Pure Mechanics).
Ghosts 'n Goblins leans a little harder on execution, though the gap is small.
19XX: The War Against Destiny
Capcom bullet density plus lock-on bomb timing
Ghosts 'n Goblins
Committed jumps and pixel-precise throws, no mercy
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
19XX: The War Against Destiny
Boss patterns are fixed
Ghosts 'n Goblins
Enemy spawns are scripted
19XX: The War Against Destiny leans a little harder on variance, though the gap is small.
19XX: The War Against Destiny
Little hidden once stages are studied
Ghosts 'n Goblins
Red Arremer movement adds slight noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
19XX: The War Against Destiny
Charge-shot usage and scoring routes reward deep study
Ghosts 'n Goblins
Weapon choice and route memorisation are mandatory
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.
