Portal placement requires some precision but timing is lenient.
Suicide Guy
Some platforming, but timing rarely strict
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

No opponent; puzzles are static.
Suicide Guy
Solo dream puzzles, no adversary
Suicide Guy leans a little harder on variance, though the gap is small.
Portal 2
Puzzles are deterministic with no randomness.
Suicide Guy
Puzzle setups are fixed, nothing random
Portal 2 leans clearly harder on optimization.
Portal 2
Solving the puzzle's logic IS the entire game.
Suicide Guy
Figuring out each dream's puzzle solution is the 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.
