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 marble-shooter testing aim and timing to match advancing colored spheres.

Execution · Practiced Mastery
Deliberate spatial puzzle-shooting stretched into randomised roguelike runs.
Luxor 3 leans Execution (Practiced Mastery); SuperHot: Mind Control Delete 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.
Luxor 3
Aiming and timing shots at moving spheres is the core
SuperHot: Mind Control Delete
Time-moves-when-you-move still demands precise spatial play
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Luxor 3
Solo - no opponent to predict
SuperHot: Mind Control Delete
Red guys follow simple deterministic behaviour
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Luxor 3
Sphere color sequences add randomness
SuperHot: Mind Control Delete
Roguelike runs randomise levels, hacks and spawns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Luxor 3
Power-up usage and chain planning improve scores
SuperHot: Mind Control Delete
Hack synergies and room-clear sequencing reward planning
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.
