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 more combat-forward sequel with sharper platforming demands.

Execution · Practiced Mastery
The notoriously demanding side-scrolling Zelda built on tight sword duels and RPG levelling.
Ori and the Will of the Wisps leans Execution (Pure Mechanics); Zelda II: The Adventure of Link leans Execution (Practiced Mastery).
Ori and the Will of the Wisps leans a little harder on execution, though the gap is small.
Ori and the Will of the Wisps
Combat plus escape chases demand tight inputs
Zelda II: The Adventure of Link
Precise sword spacing, shield stabs, brutal platforming
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ori and the Will of the Wisps
Scripted bosses, no human opponent
Zelda II: The Adventure of Link
Ironknuckles feint but follow fixed logic
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ori and the Will of the Wisps
Deterministic encounters
Zelda II: The Adventure of Link
Layouts fixed, little hidden randomness
Zelda II: The Adventure of Link leans a little harder on optimization, though the gap is small.
Ori and the Will of the Wisps
Shard loadouts and weapon choice tune playstyle
Zelda II: The Adventure of Link
XP routing, spell use, palace order planning
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.
