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.

Execution · Grand Arena
An extraction shooter where scavengers dodge killer machines and rival squads for loot.

Execution · Competitive PvP
Aim duels against humans under round rules reshuffled by random cards.
ARC Raiders leans Execution (Grand Arena); FragPunk leans Execution (Competitive PvP).
FragPunk leans a little harder on execution, though the gap is small.
ARC Raiders
Gunplay and movement under machine fire
FragPunk
Hero-shooter gunfights demand high-level aim and movement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ARC Raiders
Rival squads ambush, bait, and adapt
FragPunk
Predicting enemy pushes and card-driven adaptations is constant
ARC Raiders leans a little harder on variance, though the gap is small.
ARC Raiders
Loot spawns and unknown player positions
FragPunk
Shard Card votes reshuffle each round's rules unpredictably
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
ARC Raiders
Loadout economy and map knowledge compound
FragPunk
Hero kits and card synergies reward system study
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.
