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

Optimization · Practiced Mastery
Learning boss patterns and tuning command-deck builds with moderate action demands.

Kingdom Hearts 3D: Dream Drop Distance
Flowmotion combat asks moderate timing, rarely punishing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Kingdom Hearts 3D: Dream Drop Distance
Bosses run scripted patterns with no player modelling

Kingdom Hearts 3D: Dream Drop Distance
Dream Eater drops and spirit rolls add mild randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
