According to the plot of "Bright Sword", after many wars, he accumulated a lot of combat experience, became a general, and was able to survive and grow under extremely dangerous circumstances, while Chu was a well-educated high flyers with a solid military theoretical foundation, excellent equipment and sufficient materials.
Obviously, he is playing with ingenuity and strategy, while Chu is playing with materials and support. Military strategy and support are both decisive factors in winning or losing a war, but one is internal and the other is external.
If we put them in the same combat environment, that is, let Li Yunlong have all the materials and equipment of Yun Fei, Chu, or let Yun Fei, Chu, stay in the dangerous environment of fighting in Li Yunlong, it is obvious that Li Yunlong has stronger adaptability. Because he didn't get external conditions, he knew how to create conditions, and Chu needed to rely on external supply.
In terms of unified command, the cloud Phoebe of Chu is not on Li Yunlong. Li Yunlong led the new regiment to break through the Japanese encirclement and killed the captain of Sakata United. This is unthinkable in Chu's view, because he can't fight such an excellent battle at all. However, Chu is an outstanding graduate of Whampoa Military Academy, with a high level of operational theory and strategic vision, and he is better than others in formulating strategies.
As a matter of fact, I think Chu Yun Fei is a staff officer, and being a captain is overqualified.
