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
Team-based 5v5 Star Wars starfighter combat with cockpit power management.

Execution · Grand Arena
A classic football simulation with tactical team management.
Star Wars: Squadrons leans Execution (Grand Arena); Winning Eleven: Pro Evolution Soccer 2007 leans Execution (Grand Arena).
Star Wars: Squadrons leans a little harder on execution, though the gap is small.
Star Wars: Squadrons
Drifting, aim, and throttle tricks decide dogfights
Winning Eleven: Pro Evolution Soccer 2007
passing/shooting timing needs real precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Squadrons
Human pilots in 5v5 bait, juke, and counter-adapt
Winning Eleven: Pro Evolution Soccer 2007
human opponents adapt tactics against 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
Winning Eleven: Pro Evolution Soccer 2007
minor ball-physics randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Squadrons
Power management and loadout meta are solvable layers
Winning Eleven: Pro Evolution Soccer 2007
tactics and formations are learnable systems
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.
