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 tactical RPG solved through long-horizon build and class planning.

Optimization · Pure Optimization
Team-building optimisation against fixed trainers with mapped RNG.

Fire Emblem: Three Houses leans a little harder on execution, though the gap is small.
Fire Emblem: Three Houses

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Fire Emblem: Three Houses leans a little harder on optimization, though the gap is small.
Fire Emblem: Three Houses
Class routing and build planning dominates
Pokémon Ruby Version
Abilities and natures deepen an already solvable type system
