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

A first-person farming game about wrangling adorable slimes for plorts.

Optimization · Pure Optimization
Lineup optimisation and deploy timing against fixed stages, gated by gacha luck.
Slime Rancher leans Optimization (Pure Optimization); The Battle Cats leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Slime Rancher
Vacuum aiming is gentle.
The Battle Cats
Tapping deploy buttons with timing, minimal dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

The Battle Cats leans a little harder on variance, though the gap is small.
Slime Rancher
Plort prices and slime spawns vary.
The Battle Cats
Gacha rolls gate which cats you even own
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Slime Rancher
Ranch layout and economy reward planning.
The Battle Cats
Lineup building and deploy timing solve each stage
