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 marble-shooter testing aim and timing to match advancing colored spheres.
Doom (1993) leans Execution (Pure Mechanics); Luxor 3 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
Luxor 3
Aiming and timing shots at moving spheres is the core
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
Luxor 3
Solo - no opponent to predict
Luxor 3 leans a little harder on variance, though the gap is small.
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Luxor 3
Sphere color sequences add randomness
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
Luxor 3
Power-up usage and chain planning improve scores
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.
