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

Execution · Practiced Mastery
Anime soulslike pairing pattern-learning boss fights with flexible class builds.

Execution · Practiced Mastery
The original Souls game: scripted boss patterns you solve with builds, routes and disciplined execution.
Code Vein leans Execution (Practiced Mastery); Demon's Souls 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.
Code Vein
Dodge timing and stamina management in melee
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.
Code Vein
Bosses are scripted patterns, never 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.
Code Vein
Fixed enemy placement; minor drop randomness
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.
Code Vein
Blood codes and gift builds reward theorycraft
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.
