I think most of the times. when we have an argument, it is because we think about something differently or do something in a way which the other side would do differently. Arguing helps uncovering those differences and leads to understanding your partner. If you do it frequently, it helps you be more aware of such things. The goal is to minimize those times where you need to argue. The positive side effect of talking it through in the evening is that you can go to bed and wake up without holding a grudge. But as I said, it's not that easy and it requires both sides to be able to find a solution in a civilized way.
