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.

Execution · Practiced Mastery
An aggressive soulslike about punishing fixed boss patterns with tight dodging.

Execution · Practiced Mastery
A stance-switching action RPG where input precision meets deep loot theorycraft.
Bloodborne leans Execution (Practiced Mastery); Nioh 2 leans Execution (Practiced Mastery).
Nioh 2 leans a little harder on execution, though the gap is small.
Bloodborne
Aggressive dodges and rally timing demand sharp hands.
Nioh 2
Stance switching, ki pulse, burst counters demand inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bloodborne
Bosses follow fixed movesets; no model of you.
Nioh 2
Scripted enemies, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bloodborne
Chalice dungeon layouts and drops add some randomness.
Nioh 2
Loot drops with affix randomness
Nioh 2 leans a little harder on optimization, though the gap is small.
Bloodborne
Builds, weapons, and boss patterns are studyable and solvable.
Nioh 2
Deep build crafting and stance theorycraft central
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.
