Which one sentence of this looks better?

Yes. It is often used in technical or formal writing to avoid saying "you" (which is thought for some reason to be too casual). Instead of saying "You should make sure you engage the parking brake before exiting your car" it is written "One should make sure to engage the parking brake before exiting one's car."
