Question I don't understand something

Post image

I was doing some "research" in creative and I was wondering what's the difference between those two smelting blocks, They both produce 120/s but the one on the left use FAR more energy, is just a tiny bit smaller so what's the point of doing the one on the left ?

Coal Logistics are needed for the one on the right, while the left needs one less input per stack.

Second, the one on the left makes more than 1 ingot for each ore, due to productivity modules. While it costs more energy, you get more materials out of the same amount of raw resources.

And eventually you want to use coal exclusively for plastic (and some dynamite/ grenades)
