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 pure lane-timing reflex test against head-on collision cars.

Execution · Pure Mechanics
A classic co-op beat-em-up fantasy brawler focused on combat execution.
Dodge 'Em leans Execution (Pure Mechanics); Golden Axe II 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.
Dodge 'Em
Lane-switch timing against closing cars is the whole game
Golden Axe II
melee combo and dodge timing vs enemies
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dodge 'Em
Computer cars chase head-on by simple fixed logic
Golden Axe II
enemies run fixed scripted attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dodge 'Em
Opposing car spawns vary slightly per loop
Golden Axe II
magic potion and enemy spawn randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dodge 'Em
Optimal lane patterns are quickly learnable
Golden Axe II
character and beast-mount choice optimization
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.
