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

Execution · Pure Mechanics
A run-and-gun boss rush about dodging scripted patterns with tight inputs.

Execution · Practiced Mastery
Hornet's faster, harder metroidvania sequel built on acrobatic execution.
Cuphead leans Execution (Pure Mechanics); Hollow Knight: Silksong 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.
Cuphead
Tight dodging and parry timing decide every boss.
Hollow Knight: Silksong
Faster, harsher boss patterns demand sharper inputs
Hollow Knight: Silksong leans a little harder on reads, though the gap is small.
Cuphead
Bosses cycle scripted phases; no adaptation to player.
Hollow Knight: Silksong
Enemies are scripted, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cuphead
Minor attack-order shuffling between phases.
Hollow Knight: Silksong
Secrets and routes hidden on first run
Hollow Knight: Silksong leans a little harder on optimization, though the gap is small.
Cuphead
Loadouts and boss phase order are fully learnable.
Hollow Knight: Silksong
Tool builds and pattern mastery convert practice to wins
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.
