Portal 2Return of the Obra Dinn
Axis by axis
Execution3 vs 0
Portal 2 leans clearly harder on execution.
Portal 2
Portal placement requires some precision but timing is lenient.
Return of the Obra Dinn
No mechanical execution required
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
No opponent; puzzles are static.
Return of the Obra Dinn
Static scenes, no opponent

Puzzles are deterministic with no randomness.
Return of the Obra Dinn
Fully deterministic puzzle

Return of the Obra Dinn leans a little harder on optimization, though the gap is small.
Portal 2
Solving the puzzle's logic IS the entire game.
Return of the Obra Dinn
Pure deductive logic on a fixed manifest
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.
