head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Kirby's breezy Game Boy debut, floating and inhaling through five short dreamlike stages.

Execution · Practiced Mastery
Gentle precision platforming with puzzle rooms built around a grab-and-throw mechanic.
Kirby's Dream Land leans Execution (Practiced Mastery); Klonoa leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Dream Land
Gentle platforming, harder in Extra Mode
Klonoa
Grab-and-throw platforming needs clean but forgiving timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Dream Land
Bosses loop tiny fixed patterns
Klonoa
Enemies and bosses run fixed scripted patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Dream Land
Nothing hidden after one loop
Klonoa
Levels are identical on every attempt
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Dream Land
Short fixed levels, simple boss study
Klonoa
Collectible routes and puzzle rooms reward planning
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.
