Axis by axis
Execution1 vs 3
Portal 2 leans clearly harder on execution.
OneShot
Point-and-click pacing, no reflex test
Portal 2
Portal placement requires some precision but timing is lenient.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
OneShot
The game addresses you but never adapts strategically
Portal 2
No opponent; puzzles are static.
Variance1 vs 0
OneShot leans a little harder on variance, though the gap is small.
OneShot
Deterministic puzzle world
Portal 2
Puzzles are deterministic with no randomness.
Optimization4 vs 9
Portal 2 leans clearly harder on optimization.
OneShot
Fourth-wall puzzles have fixed solutions
Portal 2
Solving the puzzle's logic IS the entire game.
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.
