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
Dual-world soulslike where boss patterns are studied, not outsmarted.
Dark Souls III leans Execution (Practiced Mastery); Lords of the Fallen 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
Lords of the Fallen
Dodge timing and stamina discipline against bosses
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
Lords of the Fallen
Bosses are scripted movesets, 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
Lords of the Fallen
Layouts and drops mostly fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Souls III
movesets and builds are fully mappable
Lords of the Fallen
Builds, lamp routing, and moveset memorization
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.
