However, if we only look at the research of Ninjutsu and chakra, Senju Tobirama II is obviously higher than Namikaze Minato. At that time, Senju Tobirama tried to develop taboo art and tolerant art, because besides bijuu, he also hoped that Konoha had the ability to crush the enemy completely. So he developed many ninjas, and many ninjas passed down to later generations and became famous ninjas. Namikaze Minato stood on the shoulders of giants, relying on Senju Tobirama's space ninja theory to develop again, reaching today's height. Secondly, the experiences of these two people are completely incomparable. Senju Tobirama followed his brother Senju Hashirama and led the whole family to settle troubled times hand in hand.
In an era when human life is like dirt, it is very good to lead our own people to survive. It can even calm the turbulent times, in which the second generation of Huo Ying played an important role. Although not as good as Senju Hashirama and his arch-enemy Uchihiro Madara, it is obvious that Senju Tobirama can basically stand on their side on the basis of equality. If you look at this place after the resurrection, you can basically defeat Gokage, and the pillar is defeated. This is very similar to these two people, and really few people can match it.
Looking back at the fourth generation of Namikaze Minato, this may not be enough. Maybe it's fate. The so-called "fastest endurance" super ninja is always absent at critical moments. An apprentice is dead and decadent, so he can only beat some powerful players by flying Raytheon and meet real people. He really can't do anything without destructive power. Strength can contain Gokage at most. Therefore, I think the second generation of Huo Ying is more powerful than the fourth generation of Huo Ying. The above is purely a personal opinion.
