head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
A pointer-aim shooting gallery scored on accuracy and combo upkeep.

Execution · Pure Mechanics
Arcade run-and-gun reflexes against fully memorisable boss patterns.
Link's Crossbow Training leans Execution (Pure Mechanics); Sunset Riders leans Execution (Pure Mechanics).
Sunset Riders leans a little harder on execution, though the gap is small.
Link's Crossbow Training
Pointer aim speed and accuracy are literally the whole game
Sunset Riders
Dodging bullet spreads and snap-shooting bosses is everything
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
Sunset Riders
Bandits and bosses cycle memorisable arcade 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
Sunset Riders
Spawns are deterministic each credit
Sunset Riders leans a little harder on optimization, though the gap is small.
Link's Crossbow Training
Combo multipliers and spawn memorisation lift high scores
Sunset Riders
Pattern memorisation for one-credit clears is the meta-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.
