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 test of fast, precise shooting and map navigation against scripted but relentless enemies.

Execution · Practiced Mastery
A vertical scrolling shooter about upgrading your ship between bullet-hell missions.
Doom (1993) leans Execution (Pure Mechanics); Raptor: Call of the Shadows leans Execution (Practiced Mastery).
Doom (1993) leans a little harder on execution, though the gap is small.
Doom (1993)
Precise movement and shooting against relentless enemy pressure
Raptor: Call of the Shadows
dodging bullet patterns needs quick reflexes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Enemies follow scripted patrol and attack patterns, not adaptive
Raptor: Call of the Shadows
scripted enemy waves, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Raptor: Call of the Shadows
random shop upgrades between missions
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Level routing and resource management determine survival efficiency
Raptor: Call of the Shadows
ship build and upgrade optimization
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.
