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

Optimization · Systems & Chaos
Loot-shooter RPG built on gear chasing.

Optimization · Practiced Mastery

Gunplay similar to Borderlands 3
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Enemies are scripted loot fodder
Tiny Tina's Wonderlands
Scripted fantasy enemies, no reads
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Procedurally generated weapon drops vary
Tiny Tina's Wonderlands

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Skill trees and gear math heavily solved
