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
The poppy direct sequel to FFX where Yuna's trio swaps job dresspheres mid-battle across Spira.

Optimization · Pure Optimization
A puzzle-RPG hybrid where Djinn combination theory and Psynergy routing trivializes its scripted encounters.
Final Fantasy X-2 leans Optimization (Pure Optimization); Golden Sun 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.
Final Fantasy X-2
Active Time Battle rewards quick menuing slightly.
Golden Sun
Fully turn-based Djinn-based combat; no timing demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fantasy X-2
All enemies follow scripted AI routines.
Golden Sun
All bosses are scripted pattern fighters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fantasy X-2
Drop rates and unknown encounters until mapped.
Golden Sun
Djinn status randomness and summon charge timing add minor variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fantasy X-2
Dressphere builds, garment grids, and completion routing dominate.
Golden Sun
Djinn set theory, Psynergy routing, and summon sequencing are deeply solvable
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.
