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

Execution · Practiced Mastery
A bullet-hell metroidvania testing pattern dodging and build optimization against fixed bosses.
Dark Souls III leans Execution (Practiced Mastery); Tevi 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.
Dark Souls III
fast roll timing against aggressive scripted bosses
Tevi
Dodging dense bullet-hell patterns demands precise timing and movement
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
Tevi
Bosses follow fixed patterns, not adaptive prediction
Tevi leans a little harder on variance, though the gap is small.
Dark Souls III
fixed encounters converge after first sight
Tevi
Patterns are deterministic once memorized; little randomness
Dark Souls III leans a little harder on optimization, though the gap is small.
Dark Souls III
movesets and builds are fully mappable
Tevi
Build customization and pattern routing optimize boss fights
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.
