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

Optimization · Practiced Mastery
Twin-stick co-op shooter precursor.
Borderlands 2 leans Optimization (Systems & Chaos); Helldivers leans Optimization (Practiced Mastery).
Helldivers leans a little harder on execution, though the gap is small.
Borderlands 2
Aim matters but generous hit feel
Helldivers
Twin-stick aim and stratagem inputs
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
Helldivers
Scripted enemies, no real reads
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Procedurally generated weapon drops vary
Helldivers
Random spawns and patrol pressure
Borderlands 2 leans a little harder on optimization, though the gap is small.
Borderlands 2
Skill trees and gear math heavily solved
Helldivers
Loadout combos and stratagem chains
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.
