"I know." ~ Yes, a nice line, and the quintessential Han Solo can't-show-emotions response even though he's about to be freeze-dried.
However...
After being tortured to death and resuscitated, just returning to consciousness, the evil Russky says, "You died, Mr. Reynolds", Mal answers "It seemed like the thing to do." ~ This line is pure concentrated win.
Also, the combination of ranchhand/sargeant/smuggler/ship-captain that is Malcom Reynolds has so many snappy, witty, folksy from-the-dirt lines that Han instantly loses any battle of comparative dialogue. Throw in the post-Earth dystopian chinese epithets and it's game over.
