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

Optimization · Pure Optimization
A classic-styled JRPG whose brave/default system turns turns themselves into a resource.

Optimization · Pure Optimization
Fifth-generation reboot with an entirely new monster roster and stronger story.
Bravely Default leans Optimization (Pure Optimization); Pokémon Black leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Bravely Default
Turn-based menus; no physical demands
Pokémon Black
Menu battles, zero reflex demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bravely Default
Bosses follow fixed scripts
Pokémon Black
Story trainers follow fixed logic
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bravely Default
Minor drop and encounter randomness
Pokémon Black
Encounter and damage-roll randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bravely Default
Job combos and brave/default economy are deeply solvable
Pokémon Black
All-new dex forces fresh team optimization
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.
