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

Optimization · Pure Optimization
Untangling surreal fixed puzzle chains room by macabre room.

Optimization · Pure Optimization
A dark adventure game about a suicidal woman granted immortality to hunt five psychopaths.

Pointing and clicking - no dexterity involved
The Cat Lady

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rusty Lake Hotel
No opponents, only macabre puzzle rooms
The Cat Lady

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rusty Lake Hotel
Solutions are hidden until discovered, then fixed
The Cat Lady
Mild unknowns in puzzle solutions on a blind playthrough
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Chaining surreal puzzle logic per room is the whole game
The Cat Lady
Adventure-game puzzles have fixed discoverable solutions
