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 · Systems & Chaos
A short first-person horror game testing nerve against scripted home invasion scares.

Execution · Light / Casual
Chaotic physics sandbox starring a goat.
Evil leans Variance (Systems & Chaos); Goat Simulator 3 leans Execution (Light / Casual).
Goat Simulator 3 leans a little harder on execution, though the gap is small.
Evil
Walking and looking; minimal physical demand
Goat Simulator 3
Loose physics goat control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Evil
Scare events are scripted, not an adaptive mind
Goat Simulator 3
No adaptive opponents
Evil leans a little harder on variance, though the gap is small.
Evil
Hidden scares and events drive the unknown tension
Goat Simulator 3
Glitchy emergent physics events
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Evil
Figuring out what to do next is the small loop
Goat Simulator 3
Mutator and gear combo discovery
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.
