head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
A pure optimization exercise where sphere grid planning and boss weakness exploitation defines mastery.

Optimization · Pure Optimization
Hoenn's definitive version, crowned by the strategy-heavy Battle Frontier.
Final Fantasy X leans Optimization (Pure Optimization); Pokémon Emerald leans Optimization (Pure Optimization).
Final Fantasy X leans a little harder on execution, though the gap is small.
Final Fantasy X
Fully turn-based; zero time pressure on inputs
Pokémon Emerald
Turn-based commands only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fantasy X
All aeons and fiends operate on fixed AI scripts
Pokémon Emerald
Battle Frontier AI is fixed-policy
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fantasy X
Minimal RNG in base game; overdrive gauge charges predictably
Pokémon Emerald
Encounter RNG and Frontier hax
Final Fantasy X leans a little harder on optimization, though the gap is small.
Final Fantasy X
Sphere Grid routing and break damage limits make the game theoretically solvable
Pokémon Emerald
EVs, movesets, and Frontier strategy run deep
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.
