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 pointer-aim shooting gallery scored on accuracy and combo upkeep.

Execution · Pure Mechanics
Combo execution and dodge timing through scripted grindhouse brawls.
Link's Crossbow Training leans Execution (Pure Mechanics); Shank 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.
Link's Crossbow Training
Pointer aim speed and accuracy are literally the whole game
Shank
Combo juggling and dodge timing carry every brawl
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Link's Crossbow Training
Targets and enemies follow set spawn patterns
Shank
Enemies and bosses attack on fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Link's Crossbow Training
Stages replay identically for score chasing
Shank
Hand-built levels with no randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Link's Crossbow Training
Combo multipliers and spawn memorisation lift high scores
Shank
Weapon-swap combo routing rewards some lab work
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.
