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 · Competitive PvP
Combined-arms multiplayer shooter famous for map-altering levolution moments and 64-player conquest.

Execution · Grand Arena
Team-based 5v5 Star Wars starfighter combat with cockpit power management.
Battlefield 4 leans Execution (Competitive PvP); Star Wars: Squadrons leans Execution (Grand Arena).
Star Wars: Squadrons leans a little harder on execution, though the gap is small.
Battlefield 4
Gunplay, vehicle mastery, and movement under fire
Star Wars: Squadrons
Drifting, aim, and throttle tricks decide dogfights
Star Wars: Squadrons leans a little harder on reads, though the gap is small.
Battlefield 4
Human teams adapt to flanks and levolution chokes
Star Wars: Squadrons
Human pilots in 5v5 bait, juke, and counter-adapt
Battlefield 4 leans a little harder on variance, though the gap is small.
Battlefield 4
Map-altering events and spawns inject noise
Star Wars: Squadrons
Full information maps; little randomness
Star Wars: Squadrons leans a little harder on optimization, though the gap is small.
Battlefield 4
Loadout tuning and objective rotation knowledge
Star Wars: Squadrons
Power management and loadout meta are solvable layers
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.
