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 rail shooter testing reflex execution against fully memorisable enemy waves.

Execution · Practiced Mastery
An unforgiving Genesis mech shooter of memorised stages executed under fire.
Star Fox leans Execution (Practiced Mastery); Target Earth 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.
Star Fox
Dodging, shooting and barrel rolls on rails demand reflexes
Target Earth
Brutal mech run-and-gun demands precise jumps and shots
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox
Every enemy wave is a fixed scripted pattern
Target Earth
Enemy robots attack in fixed waves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox
Routes and spawns are deterministic per path
Target Earth
Stage events are scripted and memorisable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox
Memorising wave patterns and route choices for score
Target Earth
Loadout selection and learned stage routes decide survival
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.
