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 punishing retro platformer where precise jump timing is everything.

Execution · Pure Mechanics
Arcade dogfighter about staying airborne amid swarming bullets on pure stick skill.
Hudson's Adventure Island leans Execution (Pure Mechanics); Luftrausers 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.
Hudson's Adventure Island
tight platform jumps, brutal timing windows
Luftrausers
Momentum-based dogfighting demands constant precise control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hudson's Adventure Island
fixed enemy patterns, no adaptation
Luftrausers
Enemy planes follow simple fixed behaviors
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hudson's Adventure Island
fruit/egg drops randomized
Luftrausers
Spawn patterns vary slightly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Hudson's Adventure Island
level route and skateboard memorization
Luftrausers
Part combos tweak the score game
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.
