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

Optimization · Systems & Chaos
Gacha roster luck funneled into team-building optimisation against fixed encounters.

Optimization · Systems & Chaos
Solvable micro-tactics puzzles gated by gacha luck over unit ownership.
Dragonheir: Silent Gods leans Optimization (Systems & Chaos); Fire Emblem Heroes leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dragonheir: Silent Gods
Auto-leaning combat needs minimal dexterity
Fire Emblem Heroes
Drag-and-drop tactics need no dexterity
Fire Emblem Heroes leans a little harder on reads, though the gap is small.
Dragonheir: Silent Gods
PvE content and async PvP offer no live minds
Fire Emblem Heroes
Arena defense teams are AI-run, so prediction is shallow
Dragonheir: Silent Gods leans a little harder on variance, though the gap is small.
Dragonheir: Silent Gods
Gacha hero pulls and dice rolls gate power
Fire Emblem Heroes
Gacha summoning rolls gate which units you even own
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragonheir: Silent Gods
Team composition and stat tuning against fixed content is the game
Fire Emblem Heroes
Skill inheritance, team building and tile math 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.
