Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Adr1ft
Gentle zero-g drifting with mild oxygen pressure
Kirby Star Allies
Very low difficulty, AI allies carry fights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Adr1ft
No adversary exists in the wreckage
Kirby Star Allies

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Debris field layout is fixed once seen
Kirby Star Allies

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
