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.

Optimization · Light / Casual
A relaxed puzzle toy about swallowing a town with a growing hole.

Variance · Light / Casual
A choice-driven comedy adventure with almost no skill test at all.
Donut County leans Optimization (Light / Casual); Tales from the Borderlands 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.
Donut County
Moving a hole; near-zero dexterity
Tales from the Borderlands
Occasional QTEs are the only physical demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Donut County
No opponent at all
Tales from the Borderlands
No opponent of any kind
Tales from the Borderlands leans a little harder on variance, though the gap is small.
Donut County
Puzzle solutions hidden only briefly
Tales from the Borderlands
Story branches are unknown until chosen
Donut County leans a little harder on optimization, though the gap is small.
Donut County
Light swallow-order puzzles, easily solved
Tales from the Borderlands
Choices barely change outcomes; nothing to solve
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.
