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

Optimization · Practiced Mastery
The original loot-driven co-op shooter set on the bandit world of Pandora.

Optimization · Practiced Mastery
Managing a cult's economy and rituals between light roguelike combat runs.
Borderlands leans Optimization (Practiced Mastery); Cult of the Lamb: Cultist Edition leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands
Standard FPS aim; numbers matter more than precision
Cult of the Lamb: Cultist Edition
Dodge-roll combat matters but stays forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands
Bandits and skags are scripted
Cult of the Lamb: Cultist Edition
Enemies and bosses are scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands
Procedural loot drops gate your power
Cult of the Lamb: Cultist Edition
Weapon, curse and dungeon rolls vary each crusade
Cult of the Lamb: Cultist Edition leans a little harder on optimization, though the gap is small.
Borderlands
Builds, gear math, and farming routes dominate
Cult of the Lamb: Cultist Edition
Cult economy, follower loops and doctrine planning dominate
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.
