Why is Yang Jian worse than Nezha in the list of gods, but better than Nezha in Journey to the West?

In the battle of God, Yang Jian did not perform as well as Nezha. There is a reason for this. First of all, as a grain officer, Emperor Wen of Sui's main task is logistics, not fighting at the front. And Nezha is a pioneer, in the front, will let us have an illusion that Nezha is very powerful. In fact, we can get the answer from The Journey to the West. The Monkey King defeated Nezha, not because of how strong the Monkey King was, but because the Monkey King was able to handle the seventy-two changes and restrained Nezha. Yang Jian's "89 Gong Xuan" is actually an old method in 72 years, so Yang Jian can also restrain Nezha.
