head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Optimization · Practiced Mastery
Managing scarce resources between stations while clearing scripted infected with careful shots.
Borderlands leans Optimization (Practiced Mastery); The Final Station 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
The Final Station
Headshotting infected swarms with scarce ammo demands steady aim
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
The Final Station
Infected follow simple scripted rushes, never adapt
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
The Final Station
Unknown station layouts and loot until explored, then mapped
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
The Final Station
Rationing ammo, food and passenger care 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.
