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.

A relaxing hidden-object game finding cats in a holiday village.
Kholat leans Variance (Systems & Chaos); Travellin Cats in Jingle Jam 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.
