I don't know what you've heard or who from but there are several detailed scientific studies that show conclusively that there is NO mechanical advantage whatsoever to clipless pedals for non-elite riders. There is a slight argument for a small mechanical advantage in limited circumstances for very elite riders (think professionals).
the other big advantage not mentioned directly by Irwin is that you can walk around which you cannot with road shoes and cleats. You can with MTB style cleats although you still can slip on the metal cleats occasionally.
