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

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

Execution · Practiced Mastery
The divisive middle Souls game, slower and stat-heavier than its siblings.
Bloodborne leans Execution (Practiced Mastery); Dark Souls II leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Bloodborne
Aggressive dodges and rally timing demand sharp hands.
Dark Souls II
stamina and adaptability-gated dodge timing
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.
Dark Souls II
invasions add rare human mind games
Bloodborne leans a little harder on variance, though the gap is small.
Bloodborne
Chalice dungeon layouts and drops add some randomness.
Dark Souls II
fixed world, known after one trip
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bloodborne
Builds, weapons, and boss patterns are studyable and solvable.
Dark Souls II
builds and boss patterns reward study
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.
