User blog comment:Observer Supreme/How would Kizaru and Aokiji operate if either of them were Fleet Admiral?/@comment-49.146.14.220-20170718025937

They would be fine. Borsalino would be a less aggressive version of Sakazuki, but he'll have no qualms about enacting absolute justice. Kuzan would be a more peaceful fleet admiral and would probably build good ties with righteous pirates like the Strawhats or Shank's crew. They are still very responsible people and both would manage the marines well.
