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
The fastest mainline Souls, distilling the formula into aggressive boss duels.

Execution · Practiced Mastery
A melancholic metroidvania where scripted boss patterns punish imprecise dodges.
Dark Souls III leans Execution (Practiced Mastery); ENDER LILIES: Quietus of the Knights leans Execution (Practiced Mastery).
Dark Souls III leans a little harder on execution, though the gap is small.
Dark Souls III
fast roll timing against aggressive scripted bosses
ENDER LILIES: Quietus of the Knights
Dodge timing against punishing boss patterns
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls III
PvP invasions exist but are optional
ENDER LILIES: Quietus of the Knights
Bosses are scripted, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls III
fixed encounters converge after first sight
ENDER LILIES: Quietus of the Knights
Encounters fully fixed
Dark Souls III leans a little harder on optimization, though the gap is small.
Dark Souls III
movesets and builds are fully mappable
ENDER LILIES: Quietus of the Knights
Spirit loadouts, upgrades, and pattern learning
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.
