One more reason for favoring charcoal grills may be the wide range of temps you are able to achieve. A propane gas grill can't provide you with a temperature any greater than it's "high" setting. Meanwhile with charcoal you are able to arrange your charcoal to improve the cooking temperature for the cooking surface. Would you like a really temperature? Move the coals close together making a pile of these to amplify the warmth. Would you like a far more even temperature over your cooking surface? Spread the coals evenly beneath your entire cooking surface. Would you like areas to become warmer or cooler while you prepare? Just move the coals as the meat is cooking. The versatility is a lot greater having a charcoal grill than the usual propane gas grill. Bear in mind you are able to adjust the dials on the propane gas grill, however, you can't move in which the heating elements are.
