head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A space dogfighter testing drift maneuvers and tracking aim against scripted squadrons.

Execution · Pure Mechanics
The 70s-cinema getaway driving game with famously demanding physics.
Chorus leans Execution (Pure Mechanics); Driver 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.
Chorus
Drift turns and dogfight aim are the whole combat test
Driver
Handbrake control and pursuit driving by feel
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Chorus
Enemy pilots fly scripted AI routines
Driver
Police AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Chorus
Little hidden beyond unexplored map corners
Driver
Traffic adds mild unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Chorus
Weapon swapping and upgrade picks add a light layer
Driver
City routes and mission tactics 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.
