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

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

Optimization · Pure Optimization
A roguelite dungeon-crawler fused with a cult management sim.
Borderlands leans Optimization (Practiced Mastery); Cult of the Lamb leans Optimization (Pure Optimization).
Borderlands leans a little harder on execution, though the gap is small.
Borderlands
Standard FPS aim; numbers matter more than precision
Cult of the Lamb
Roguelite combat needs decent dodges.
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
Enemies are scripted, not 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
Run rooms and tarot pulls randomize.
Cult of the Lamb leans a little harder on optimization, though the gap is small.
Borderlands
Builds, gear math, and farming routes dominate
Cult of the Lamb
Cult management and build synergies 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.
