Outlast leans a little harder on execution, though the gap is small.
Iron Lung
Slow submarine piloting by coordinates
Outlast
Running, hiding, and camera use.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Variance3 vs 2
Iron Lung leans a little harder on variance, though the gap is small.
Iron Lung
Blind navigation; you see only camera snapshots
Outlast
Mild patrol variance.

Outlast
Battery and route planning shallow.
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.
