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
WWII squad-tactics RTS where cover micro, sector pressure, and doctrine counters form an interlocking test.

Execution · Grand Arena
Build-fight battle royale with deep mechanics.
Company of Heroes leans Execution (Grand Arena); Fortnite leans Execution (Grand Arena).
Fortnite leans a little harder on execution, though the gap is small.
Company of Heroes
Infantry cover micro and suppression-break timing are precise demands
Fortnite
Build-edit-aim combos punish slow hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Company of Heroes
Opponent sector pushes and doctrine choices must be predicted
Fortnite
Box fights are pure adaptive mind games
Fortnite leans a little harder on variance, though the gap is small.
Company of Heroes
Reinforcement point capture variance and munitions drops add uncertainty
Fortnite
Loot drops, storm, item rotations vary
Company of Heroes leans a little harder on optimization, though the gap is small.
Company of Heroes
Resource point priority and doctrine selection are learnable systems
Fortnite
Loadouts, mats economy, rotations solvable
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.
