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.

Variance · Light / Casual
A painterly hidden-object game testing visual scanning patience.

Variance · Light / Casual
A first-person psychological horror set in a cursed family home.
Under Leaves leans Variance (Light / Casual); Visage leans Variance (Light / Casual).
Visage leans a little harder on execution, though the gap is small.
Under Leaves
Tapping spotted objects requires nothing physical
Visage
Slow movement and item use.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Under Leaves
No opponent exists
Visage
Ghosts follow scripted triggers.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Under Leaves
Object locations are hidden until found - that is the game
Visage
Some scares and item placements vary.
Visage leans a little harder on optimization, though the gap is small.
Under Leaves
Systematic scanning is the only technique
Visage
Sanity management is shallow.
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.
