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 rail shooter testing pointer accuracy against fully memorisable enemy scripts.

Execution · Practiced Mastery
A rail shooter testing reflex execution against fully memorisable enemy waves.
Blue Estate leans Execution (Pure Mechanics); Star Fox leans Execution (Practiced Mastery).
Blue Estate leans a little harder on execution, though the gap is small.
Blue Estate
Aim accuracy under on-rails time pressure is the entire test
Star Fox
Dodging, shooting and barrel rolls on rails demand reflexes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blue Estate
Enemies pop up on fixed scripts, never adapting
Star Fox
Every enemy wave is a fixed scripted pattern
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blue Estate
Spawn sequences are identical every run
Star Fox
Routes and spawns are deterministic per path
Star Fox leans a little harder on optimization, though the gap is small.
Blue Estate
Memorising spawn order and scoring multipliers raises grades
Star Fox
Memorising wave patterns and route choices for score
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.
