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

Optimization · Pure Optimization
The most mechanically varied Danganronpa trial system, wrapping a meta-narrative puzzle about fiction and truth.

Optimization · Pure Optimization
Gentleman puzzler solves a village full of standalone brainteasers.
Danganronpa V3: Killing Harmony leans Optimization (Pure Optimization); Professor Layton and the Curious Village leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Danganronpa V3: Killing Harmony
New Debate Scrum and other trial modes add mild timing
Professor Layton and the Curious Village
Stylus taps only; no dexterity pressure at all
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Danganronpa V3: Killing Harmony
Culprits are predetermined; no adaptive deduction layer
Professor Layton and the Curious Village
No opponent, adaptive or otherwise
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Danganronpa V3: Killing Harmony

Professor Layton and the Curious Village
Puzzle answers are hidden until reasoned out, then fixed
Professor Layton and the Curious Village leans a little harder on optimization, though the gap is small.
Danganronpa V3: Killing Harmony
Mastering all trial minigames and argument logic is the optimisable path
Professor Layton and the Curious Village
Every brainteaser has one clean solvable answer
