This is true as well.
Fujitora's existence takes a shit on Garp's entire character. Garp had plenty cloud to do something against the CD in all those decades.
It was said that they weren't capable to get rid of Garp because of how popular he got with the people.
Fujitora came in as a nobody and managed to get rid of the balance and then literally freed slaves and helped them escape.
There are levels.
What it shows us that Fujitora is a very formidable political player. It doesn't say anything about his power compared to Dragon or the other Admirals. It is also possible he is the only one that could get away with what he is doing due to being blind and pretending to be slow. Humans always underestimate someone like that.

Sengoku was unquestioned leader for years hailed for his strategic mind, Kong has climbed even beyond FA (could be due to being a yes man though) and Fujitora has in no time gotten his will through outsmarting Akainu and only gotten found out by the GOAT Sengoku.
Akainu and Aokiji both are able to lead but they can't unite the Marines leading to factions.
Garp has loyal followers but he is way too rash and lacks smart ways to dupe his superiors to get his will through.
Kizaru and Aramaki follow rather than lead.
Dragon probably is more of a leader in opposition than a savvy including leader. Likely rather fights it from outside than smartly from the inside like Fujitora.
