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

Optimization · Pure Optimization
A first-person farming game about wrangling adorable slimes for plorts.
Neighbours from Hell leans Optimization (Pure Optimization); Slime Rancher leans Optimization (Pure Optimization).
Neighbours from Hell leans a little harder on execution, though the gap is small.
Neighbours from Hell
Timing pranks between patrol windows
Slime Rancher
Vacuum aiming is gentle.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell
The neighbour loops a fixed routine
Slime Rancher
Slimes follow scripted behaviors.
Slime Rancher leans a little harder on variance, though the gap is small.
Neighbours from Hell
Routine unknown on first attempt, then converges
Slime Rancher
Plort prices and slime spawns vary.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell
Sequencing pranks for maximum combo rating
Slime Rancher
Ranch layout and economy reward planning.
