What is the sound of one piston slapping?

I know it that it has the benefits in traction during inclement weather conditions (tons of recent articles about drive wheels vs proper tires have flooded this site) but what are the other benefits?

Also my main question would be what are the drawbacks? Any particular maintenance issues I need to worry about. The vehicle in question is a Ford Flex w/ AWD. My old man wants me to get AWD but I think FWD would do just fine for me.
