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
Dodging scripted bullet patterns with stage memorisation doing the planning.

Execution · Pure Mechanics
An open-world extreme sports game about carving ski, snowboard, and wingsuit lines down the Alps.
Air Buster leans Execution (Pure Mechanics); Steep leans Execution (Pure Mechanics).
Air Buster leans a little harder on execution, though the gap is small.
Air Buster
Bullet weaving and tight corridors demand precise control
Steep
Landing tricks and threading lines at speed is hands-first
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Air Buster
Enemy waves are fully scripted patterns
Steep
The mountain never adapts to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Air Buster
Spawns are deterministic once a credit is studied
Steep
Fixed terrain, deterministic physics
Air Buster leans a little harder on optimization, though the gap is small.
Air Buster
Memorising stage layouts and power-up routes drives clears
Steep
Line choice and trick scoring math reward study
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.
