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
Gentle precision platforming with puzzle rooms built around a grab-and-throw mechanic.

Execution · Practiced Mastery
Gentle collect-and-glide platforming with light routing depth.
Klonoa leans Execution (Practiced Mastery); Spyro the Dragon 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.
Klonoa
Grab-and-throw platforming needs clean but forgiving timing
Spyro the Dragon
Gliding and charging need modest precision at most
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Klonoa
Enemies and bosses run fixed scripted patterns
Spyro the Dragon
Gnorcs repeat one behaviour forever
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Klonoa
Levels are identical on every attempt
Spyro the Dragon
Gem locations are fixed once levels are explored
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Klonoa
Collectible routes and puzzle rooms reward planning
Spyro the Dragon
Collection routing and glide lines reward light 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.
