Rayleigh is the vice captain, Beckman is the vice captain, the strawhats don't really have commanders in the traditional sense, though Zoro was portrayed as being like the vice captain to the crew. Guys like Yasopp and Roo are commanders, the calamities are commanders, the sweet commanders are commanders. Oden technically joined as a commander, but contrary to the other commanders being his children, he joined as Whitebeard's brother.
King doesn't really stand out as a commander. He has no special standing. And yes, Aramaki destroyed King and Queen. Although King wasn't at this strongest, he looked pitiful. Aramaki had zero struggle even though he handled Queen at the same time.
This doesn't look like he "couldn't do shit":
Why the hate against King, my man?
Let's be real, even if King has his Devil Fruit (DF) deactivated, he can still rely on his racial abilities, which allow him to last long enough against any Top Tier. Unlike, for example, Marco, who is extremely dependent on his DF.

Oda really failed to portray this consistently; however, there's that scene where King summons the Tobi Roppo to go after Yamato for Kaidou. It's true that he used Kaidou's name, but the emphasis here is on his attitude, showing that he's different. Of course, the Tobi Roppo members can't respect him because everything revolves around a hierarchy in which King is at the top as a Calamity (Beast Pirates commander). The members who hold this title include Jack, who is considered the younger brother of King and Queen, and Queen, who was practically fawning over King and his powers during the fight against Sanji.

LOL, this isn't the Comrade I know. Did you notice how X-Drake is still bedridden after the events in Wano? And X-Drake took much less powerful attacks than King. Even Marco, who is known for his regeneration and being a mythical Zoan like Luffy, was covered in bandages and, according to Shanks' words, exhausted. And all this, combined with the fact that the guy was without:
- One of his wings
- His sword to channel his attacks like the Imperial Dragon.
Yes, I know this disadvantage could have been compensated by adding Queen to help him, but Queen shared the same issues, and of course, there’s the fact that Green Bull's approach towards King and Queen was completely hidden from us.
