Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Black the Fall
Some timed stealth and chase sections demand light precision
Silent Hill: Homecoming
Dodge-and-counter combat needs modest timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black the Fall
Guards and machines run fixed detection scripts
Silent Hill: Homecoming
Monsters attack on fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Puzzle mechanics are unknown until each trial-and-error death
Silent Hill: Homecoming
First-run layouts and ambushes hide information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Each room is a fixed puzzle with one solution
Silent Hill: Homecoming
Enemy patterns and routes are learnable
