I'd agree with you, for substantial weight
What I mean is, the weight of the clothes sit on your shoulders (which is a negligible amount), which i find much more comfortable than the weight on the hips (and the constriction required to keep pants from falling off).
Also, if you have a heavy tool like a cordless drill, you can hook them on overalls (to free up your hands) and the added weight won't pull them down, unlike pants
