We know from historical records that Zhuge Liang helped Liu Bei conquer the world, but it did not end well in the end, and the Kingdom of Shu also perished. As for the other Liu Bowen, with his help Zhu Yuanzhang unified the world and established the Ming Dynasty. Although we can see from the endings of these two men that Liu Bowen was more successful, the historical fact is that Zhuge Liang was more powerful.
Both Zhuge Liang and Liu Bowen were very knowledgeable counselors, but their choices were very different. Zhuge Liang was born in the war-torn Three Kingdoms. It was an era when stars were competing for victory. Although Zhuge Liang knew that Liu Bei was not the most suitable master at that time, he could not wait any longer. This fact of being born at the wrong time is vividly reflected in Zhuge Liang. But Liu Bowen is better off. Following the powerful Zhu Yuanzhang, he will be a financial backer. The main reason is that Zhu Yuanzhang not only has Liu Bowen, but also other wizards in various fields to help him win the world. In this way, Liu Bowen is more promising than Zhuge Liang, but Zhuge Liang was able to help Liu Bei gain three-thirds of the world's power in that situation. It is not difficult to see his strength.
At that time, Zhuge Liang chose to assist Liu Bei with all his heart after Liu Bei visited his thatched cottage three times. Later, even though he knew that Liu Bei was the weakest among the forces at that time, he did not vote for another master and devoted himself to serving Liu Bei. Liu Bei made suggestions. Moreover, Zhuge Liang also had many opponents in the enemy camp. There are Sima Yi, Cao Wei's five counselors, Lu Su, Lu Xun, Lu Meng, etc. who are also opponents of top counselors. Liu Bowen was much more relaxed in this regard. Zhu Yuanzhang not only had Liu Bowen, he also had Zhu Sheng who proposed the nine-character strategy for him, and Li Shanchang who was good at governing the country and others to give him advice.
So I think Zhuge Liang is more powerful than Liu Bowen.
