Because it certainly feels that way compared to most Marine Ranks , with the likes of John Giant Ordering The Buster Call VA around implying a Hierarchy, Doflamingo trolling Two Vice Admirals but being terrified of Tsuru, Aokiji stomping Saul when they were both Vice Admirals, Kizaru having the ability to influence who becomes a warlord as a Vice Admiral. This isn't to mention the 3 Zodiacs who have a Real life Actor inspiration and Color/Animal Theme much like the Admirals(granted Tensei isn't a Marine Officer)
A lot of this would have been fixed by splitting the Rank into two, with Momonga or Vergo being the Strongest of the Weaker Rank and the stronger Rank being reserved for minimally Jack level guys with the Stronger officers being people who are one or two stat upgrade away from Admiral level.
