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
Memorising scripted bullet waves and executing clean dodges for score.

Execution · Practiced Mastery
Neon top-down massacre where each floor is a one-mistake execution puzzle.
Aero Fighters 3 leans Execution (Practiced Mastery); Hotline Miami 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.
Aero Fighters 3
Dodging dense bullet patterns is the whole challenge
Hotline Miami
One-hit-death rooms demand flawless fast inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Aero Fighters 3
Enemy waves are fully scripted, nothing adapts
Hotline Miami
Enemies are dumb scripted reactors
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Aero Fighters 3
Minor item drops aside, patterns are fixed once learned
Hotline Miami
Slight enemy behavior wobble between restarts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Aero Fighters 3
Memorising spawns, routes and ship choice drives high scores
Hotline Miami
Route planning and mask choice per floor
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.
