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 3D platformer where tight jumps and reflexes carry level completion.

Execution · Pure Mechanics
The 70s-cinema getaway driving game with famously demanding physics.
Crash Bandicoot: The Wrath of Cortex 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.
Crash Bandicoot: The Wrath of Cortex
precise platforming and timing required
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.
Crash Bandicoot: The Wrath of Cortex
scripted enemies, no adaptation
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.
Crash Bandicoot: The Wrath of Cortex
minimal randomness
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.
Crash Bandicoot: The Wrath of Cortex
level routes and collectibles solvable
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.
