head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Grand Arena
Build-fight battle royale with deep mechanics.

Execution · Competitive PvP
Aim duels against humans under round rules reshuffled by random cards.
Fortnite leans Execution (Grand Arena); FragPunk leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fortnite
Build-edit-aim combos punish slow hands
FragPunk
Hero-shooter gunfights demand high-level aim and movement
Fortnite leans a little harder on reads, though the gap is small.
Fortnite
Box fights are pure adaptive mind games
FragPunk
Predicting enemy pushes and card-driven adaptations is constant
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fortnite
Loot drops, storm, item rotations vary
FragPunk
Shard Card votes reshuffle each round's rules unpredictably
Fortnite leans a little harder on optimization, though the gap is small.
Fortnite
Loadouts, mats economy, rotations solvable
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.
