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
Split-attention aiming and flying through fixed, memorizable rail-shooter stages.
Crash Bandicoot: The Wrath of Cortex leans Execution (Pure Mechanics); Star Fox Zero 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
Star Fox Zero
Dual-screen aiming while flying is the central demand
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
Star Fox Zero
Enemy squadrons fly scripted routes
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
Star Fox Zero
Levels replay identically every run
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
Star Fox Zero
Score routes and medal paths reward memorization
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.
