Think of it this way: You are tasked with moving eight 10 lb rocks from one end yard to the other by carrying them. Eight trips with a 10 lb rock is relatively easy. Four trips with two 10 lb rocks is harder but still doable. Two trips with four 10 lb rocks would be hard but is a whole lot harder. See where I’m going? A single trip takes a whole lot more effort than any of those other methods. Same work, same energy input (ignore the return trip) but, from a physiological perspective, it’s a whole lot harder to do one trip.
Lemme see if I can explain it using your rock metaphor: the OP is asking whether there's any difference in how hard it is to move 8 10 lb rocks in one trip with a wheelbarrow, vs 10 8 lb rocks in the same wheelbarrow. And your response is that most people prefer 8 lb rocks over 10 lb rocks.
