If you have to compete, personally, Peng ranks first.
Although Zhu De ranked first among the top ten marshals, largely because Zhu De had always been the supreme commander of the army, during the Eighth Route Army, almost all battles were directly commanded by Peng. Peng is also Lin Biao's superior. In the army, qualifications are very important. In this respect, Peng is slightly better than Lin Biao.
Peng also had an impressive record of defeating the "United Nations Army" led by the United States in the War to Resist US Aggression and Aid Korea. The battlefield environment can't be compared with the civil war, nor can it be compared with Lin Biao.
