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
A melancholy 2.5D platformer where Klonoa hurls grabbed enemies to double-jump through dream worlds.

Execution · Practiced Mastery
A 3D Sonic where you swap between three-character team formations mid-level.
Klonoa: Door to Phantomile leans Execution (Practiced Mastery); Sonic Heroes 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: Door to Phantomile
Enemy-grab double jumps need precise timing
Sonic Heroes
Speed sections punish sloppy control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Klonoa: Door to Phantomile
Purely scripted enemies and bosses
Sonic Heroes
Scripted enemies only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Klonoa: Door to Phantomile
Dream stone spots are fixed
Sonic Heroes
Fixed level layouts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Klonoa: Door to Phantomile
Puzzle-platforming routes have clean solutions
Sonic Heroes
Team-formation switching and rank routes
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.
