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.

Execution · Competitive PvP
A sprawling military simulator where realistic ballistics and planning beat reflexes.

Execution · Practiced Mastery
A hardcore open-world survival game where other prisoners are the real threat.
Arma 2 leans Execution (Competitive PvP); SCUM leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Arma 2
Ballistics, stance, and positioning over twitch aim
SCUM
Realistic gunplay and ballistics punish poor aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Arma 2
Human squads in PvP scenarios adapt
SCUM
Human players ambush and adapt across the island
SCUM leans a little harder on variance, though the gap is small.
Arma 2
Vast terrain hides enemy positions
SCUM
Loot spawns and unseen players create constant unknowns
SCUM leans a little harder on optimization, though the gap is small.
Arma 2
Doctrine, loadouts, and mission planning
SCUM
Deep metabolism and gear systems reward planning
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.
