head to head
Star Wars: Squadrons asks more than Top Spin 4, and the gap is optimization.

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

Execution · Pure Mechanics
A simulation tennis game built around precise shot-timing rallies.
Star Wars: Squadrons leans Execution (Grand Arena); Top Spin 4 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Squadrons
Drifting, aim, and throttle tricks decide dogfights
Top Spin 4
Shot timing meter decides every rally
Star Wars: Squadrons leans a little harder on reads, though the gap is small.
Star Wars: Squadrons
Human pilots in 5v5 bait, juke, and counter-adapt
Top Spin 4
Human PvP rewards anticipating placement habits
Star Wars: Squadrons leans a little harder on variance, though the gap is small.
Star Wars: Squadrons
Full information maps; little randomness
Top Spin 4
Almost no randomness in ball physics
Star Wars: Squadrons leans clearly harder on optimization.
Star Wars: Squadrons
Power management and loadout meta are solvable layers
Top Spin 4
Player builds and court tactics are learnable
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.
