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
Soulslike action RPG retelling Journey to the West through spectacular boss gauntlets.

Execution · Practiced Mastery
The original Souls game: scripted boss patterns you solve with builds, routes and disciplined execution.
Black Myth: Wukong leans Execution (Practiced Mastery); Demon's Souls leans Execution (Practiced Mastery).
Black Myth: Wukong leans a little harder on execution, though the gap is small.
Black Myth: Wukong
Dodge timing and stagger management against bosses
Demon's Souls
Stamina-timed dodges and parries punish sloppy hands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black Myth: Wukong
Bosses are scripted movesets, not adaptive
Demon's Souls
Invasions exist but bosses are scripted patterns.
Demon's Souls leans a little harder on variance, though the gap is small.
Black Myth: Wukong
Fixed encounters; minor secret discovery
Demon's Souls
World tendency and upgrade drops add mild noise.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Black Myth: Wukong
Spell builds, transformations, and moveset study
Demon's Souls
Builds, routes and learned movesets are fully solvable.
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.
