head to head
StarCraft II: Wings of Liberty asks more than Star Wars: Squadrons, and the gap is reads.

Execution · Grand Arena
Team-based 5v5 Star Wars starfighter combat with cockpit power management.

Execution · Grand Arena
Real-time strategy where hands, reads, and build optimization all matter at the top.
Star Wars: Squadrons leans Execution (Grand Arena); StarCraft II: Wings of Liberty leans Execution (Grand Arena).
StarCraft II: Wings of Liberty leans a little harder on execution, though the gap is small.
Star Wars: Squadrons
Drifting, aim, and throttle tricks decide dogfights
StarCraft II: Wings of Liberty
APM, macro, micro-control under pressure
StarCraft II: Wings of Liberty leans clearly harder on reads.
Star Wars: Squadrons
Human pilots in 5v5 bait, juke, and counter-adapt
StarCraft II: Wings of Liberty
1v1 ladder vs adaptive humans modeling you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Squadrons
Full information maps; little randomness
StarCraft II: Wings of Liberty
map spawns minor; mostly known
StarCraft II: Wings of Liberty leans clearly harder on optimization.
Star Wars: Squadrons
Power management and loadout meta are solvable layers
StarCraft II: Wings of Liberty
build orders, economy curves heavily solved
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.
