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.

Optimization · Practiced Mastery
A combat-forward Silent Hill entry with dodge-based melee and branching endings.

Optimization · Practiced Mastery
Open-world Hyrule built on physics puzzles and exploration over reflex tests.
Silent Hill: Homecoming leans Optimization (Practiced Mastery); The Legend of Zelda: Breath of the Wild leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Hill: Homecoming
Dodge-and-counter combat needs modest timing
The Legend of Zelda: Breath of the Wild
Parry timing and aiming matter but forgiving.
The Legend of Zelda: Breath of the Wild leans a little harder on reads, though the gap is small.
Silent Hill: Homecoming
Monsters attack on fixed patterns
The Legend of Zelda: Breath of the Wild
Enemies follow fixed scripted behaviors.
Silent Hill: Homecoming leans a little harder on variance, though the gap is small.
Silent Hill: Homecoming
First-run layouts and ambushes hide information
The Legend of Zelda: Breath of the Wild
Weapon drops and weather lightly randomized.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Hill: Homecoming
Enemy patterns and routes are learnable
The Legend of Zelda: Breath of the Wild
Shrines, cooking, traversal routes fully solvable.
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.
