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

Optimization · Pure Optimization
Investigation and deduction-tree logic with token action interludes.

Optimization · Pure Optimization
A recruitment RPG where building your 108-star army and optimizing rune strategies is the strategic spine.
Sherlock Holmes: The Devil's Daughter leans Optimization (Pure Optimization); Suikoden 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.
Sherlock Holmes: The Devil's Daughter
Occasional action minigames, mostly trivial
Suikoden
Basic menu combat with minimal timing sensitivity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sherlock Holmes: The Devil's Daughter
Suspects are written characters, not adapting minds
Suikoden
All enemies scripted; castle battles use fixed logic
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sherlock Holmes: The Devil's Daughter
Case clues are hidden until investigated
Suikoden
Random encounters and some rune drop RNG add minor chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sherlock Holmes: The Devil's Daughter
Deduction-tree reasoning from gathered evidence is the game
Suikoden
108 Stars recruiting order and rune attachment optimization define efficient runs
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.
