Smokers
If you look at the hardcover rib competition smokers. Most agree charcoal wins the flavor contest. Those who prefer a more smokey taste prefer wood burners. (With a wide variety of material debate.) Propane probably wins the consistency debate. Electric only wins the ease of operation decision.
I personally prefer charcoal. One for taste. And I'm most familiar. (Certainly do not discount familiarity. If you are good with one? And it works? Stay with it.)
