head to head
Neither is simply harder - they are hard in different places. Borderlands 2 demands more execution; Cloverpit demands more variance.

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

Variance · Systems & Chaos
Engineering perk synergies to beat a slot machine's RNG before the debt does.
Borderlands 2 leans Optimization (Systems & Chaos); Cloverpit leans Variance (Systems & Chaos).
Borderlands 2 leans clearly harder on execution.
Borderlands 2
Aim matters but generous hit feel
Cloverpit
Pulling a slot lever takes nothing
Borderlands 2 leans a little harder on reads, though the gap is small.
Borderlands 2
Enemies are scripted loot fodder
Cloverpit

Cloverpit leans clearly harder on variance.
Borderlands 2
Procedurally generated weapon drops vary
Cloverpit
Slot spins and perk offers drive every run's fate
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Cloverpit
Stacking synergistic perks to beat the debt is the real game
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.
