head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
A precision metroidvania about learning fixed boss patterns and tight platforming.

Execution · Practiced Mastery
Twitchy cover-shooter rooms that reward drilled execution and memorised routes.
Hollow Knight leans Execution (Practiced Mastery); Not a Hero 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.
Hollow Knight
Precise platforming and pogo timing dominate hard content.
Not a Hero
Slide-cancels, snap cover and reload timing decide every room
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Bosses run scripted attack pools; not adaptive.
Not a Hero
Enemies follow fixed behaviours, nothing adapts to you
Not a Hero leans a little harder on variance, though the gap is small.
Hollow Knight
Negligible; world layout is fixed.
Not a Hero
Minor enemy spawn jitter, levels otherwise deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Charm builds and boss routes are fully learnable.
Not a Hero
Learning room layouts and routing kills enables full-clear runs
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.
