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

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Still Life
Pointing and clicking carries no physical demand
The Tiny Bang Story
Clicking hidden objects has no physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Still Life
The killer is a fixed narrative, not an adapting opponent
The Tiny Bang Story

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Still Life
Inventory puzzles and deduction steps have fixed solutions
The Tiny Bang Story
Each machine puzzle has one fixed deducible solution
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.
