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 · Competitive PvP
Milsim 50v50 team-tactical shooter.

Execution · Grand Arena
Team-based 5v5 Star Wars starfighter combat with cockpit power management.
Squad leans Execution (Competitive PvP); Star Wars: Squadrons leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Squad
Bullet drop, sway, suppression test aim
Star Wars: Squadrons
Drifting, aim, and throttle tricks decide dogfights
Squad leans a little harder on reads, though the gap is small.
Squad
Squad tactics versus humans demand prediction
Star Wars: Squadrons
Human pilots in 5v5 bait, juke, and counter-adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Squad
Minimal RNG, comm-driven outcomes
Star Wars: Squadrons
Full information maps; little randomness
Star Wars: Squadrons leans a little harder on optimization, though the gap is small.
Squad
Logistics, FOB placement, kit choice deep
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.
