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 · Pure Mechanics
High-volume shooting accuracy through chaotic scripted raids.

Execution · Practiced Mastery
Massive persistent-war FPS where hundreds of players contest continents simultaneously.
Delta Force: Black Hawk Down leans Execution (Pure Mechanics); PlanetSide 2 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.
Delta Force: Black Hawk Down
Fast aim against dense hostile crowds is the core test
PlanetSide 2
Gunplay and vehicle piloting at FPS standards
PlanetSide 2 leans a little harder on reads, though the gap is small.
Delta Force: Black Hawk Down
Large multiplayer servers add human positioning play
PlanetSide 2
Human enemies adapt, diluted across hundreds
PlanetSide 2 leans a little harder on variance, though the gap is small.
Delta Force: Black Hawk Down
Spawning enemy placements vary slightly between attempts
PlanetSide 2
Massive battles produce constant chaos
PlanetSide 2 leans a little harder on optimization, though the gap is small.
Delta Force: Black Hawk Down
Loadout choice and mission routes are learnable
PlanetSide 2
Loadouts, terrain, and territory strategy matter
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.
