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
A horror adventure testing puzzle deduction through scripted scares.

Optimization · Pure Optimization
Open-world detective work testing evidence deduction without hand-holding.
The Long Reach leans Optimization (Pure Optimization); The Sinking City 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.
The Long Reach
Light evasion sequences barely tax the hands
The Sinking City
Clunky combat is deliberately undemanding
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Long Reach
Scripted horror encounters never adapt to you
The Sinking City
Monsters and citizens follow fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Long Reach
Story twists and puzzle states are hidden until discovered
The Sinking City
Case clues are hidden information until investigated
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Long Reach
Item-puzzle chains have single fixed solutions to work out
The Sinking City
Cross-referencing evidence and city archives is the deduction core
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.
