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 · Practiced Mastery
A looter shooter where build optimization gates raid and seasonal content.

Optimization · Practiced Mastery
An action roguelike about building boon synergies while dodging scripted encounters.
Destiny 2 leans Optimization (Practiced Mastery); Hades leans Optimization (Practiced Mastery).
Hades leans a little harder on execution, though the gap is small.
Destiny 2
Gunplay matters but raids forgive mechanics.
Hades
Dash-attack timing and dodging drive moment-to-moment fights.
Destiny 2 leans a little harder on reads, though the gap is small.
Destiny 2
PvE is scripted; Crucible has light adaptation.
Hades
Enemies and bosses use scripted patterns, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Destiny 2
Loot drops and rolls drive the chase.
Hades
Boon offers and room rewards randomise each run.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Destiny 2
Build crafting, mods, and damage rotations dominate.
Hades
Build synergies and weapon aspects are deep solvable theory.
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.
