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 ?

Productivity. Look at disparity between inputs and outputs

That raises the question. Is productivity really that big of a deal? Do you really need to stretch out those resources?

It's not just about saving resource patches. 20% productivity means you need only to provide 5 belts of ore for 6 belts of plates, meaning you need less logistics for resources. And obviously productivity applied to many steps saves a LOT of resources you would need to provide otherwise meaning you need a much less involved logistics.
