head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Sequel sharpening the penitent metroidvania formula with three distinct weapons.

Execution · Practiced Mastery
The fastest mainline Souls, distilling the formula into aggressive boss duels.
Blasphemous 2 leans Execution (Practiced Mastery); Dark Souls III 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.
Blasphemous 2
Multi-weapon combat timing and platforming challenges
Dark Souls III
fast roll timing against aggressive scripted bosses
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous 2
Scripted boss movesets, never adaptive
Dark Souls III
PvP invasions exist but are optional
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous 2
Fixed world with hidden secrets
Dark Souls III
fixed encounters converge after first sight
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous 2
Weapon choice, altarpiece builds, and routing
Dark Souls III
movesets and builds are fully mappable
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.
