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

Variance · Systems & Chaos
Map-and-compass navigation through hidden dangers on a hostile mountain.

Variance · Systems & Chaos
A relaxed visual search for hidden cats in a fixed illustrated scene.
Kholat leans Variance (Systems & Chaos); Travellin Cats in Paris leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Kholat
Walking the mountain takes no dexterity
Travellin Cats in Paris
Pointing and clicking at a leisurely pace
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kholat
The presence stalks on randomised triggers, not a mind
Travellin Cats in Paris
A static illustration cannot adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kholat
Navigating by map coordinates with hidden danger zones
Travellin Cats in Paris
Cat hiding spots are unknown until spotted
Kholat leans a little harder on optimization, though the gap is small.
Kholat
Landmark navigation and route memory converge with repetition

Systematic screen-scanning is the only technique
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.
