head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, 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
Time-looping sequel that doubles down on the swarm-shooting and weapon-farming loop.

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
Earth Defense Force 6
Swarm kiting and aim across four classes
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
Earth Defense Force 6
Enemies remain scripted swarm AI
Borderlands leans a little harder on variance, though the gap is small.
Borderlands
Procedural loot drops gate your power
Earth Defense Force 6
RNG weapon drops and armor farming
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands
Builds, gear math, and farming routes dominate
Earth Defense Force 6
Loadout theory and mission-specific strategies
