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

Variance · Light / Casual
A sci-fi mystery visual novel where survivors trapped in an underwater park unravel a layered truth.

Variance · Light / Casual
An exploration of narrative branches that deliberately tests nothing.
Ever 17: The Out of Infinity leans Variance (Light / Casual); The Stanley Parable leans Variance (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Ever 17: The Out of Infinity
Reading only, no inputs of skill
The Stanley Parable
Walking is the only input
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ever 17: The Out of Infinity
No adaptive opposition
The Stanley Parable
The narrator is a script, however much he pretends otherwise
Ever 17: The Out of Infinity leans a little harder on variance, though the gap is small.
Ever 17: The Out of Infinity
Hidden narrative truth and locked routes drive first-run mystery
The Stanley Parable
Endings are hidden information until you wander into them
Ever 17: The Out of Infinity leans a little harder on optimization, though the gap is small.
Ever 17: The Out of Infinity
Flag and route ordering to unlock the true ending
The Stanley Parable
Finding all branches is a trivial checklist
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.
