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

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

Execution · Practiced Mastery
An open-world soulslike about pattern-learning bosses while engineering a strong build.
Bloodborne leans Execution (Practiced Mastery); Elden Ring 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.
Elden Ring
Dodge timing and weapon spacing carry every fight.
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.
Elden Ring
Bosses use scripted movesets with delayed timings, not 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.
Elden Ring
Open-world drops and rune farms add mild randomness.
Elden Ring leans a little harder on optimization, though the gap is small.
Bloodborne
Builds, weapons, and boss patterns are studyable and solvable.
Elden Ring
Build crafting, routes, and boss patterns are deeply learnable.
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.
