So during this raid Queen not only successfully infected his allies with the virus and then even lost the only cure to the enemy but he also managed to make the underlings switch sides so that their number advantage gets smaller. King wasn’t kidding, Queen is so incompetent that it Is hard to get even mad at another thing he screws up
Jack at least TRIES to make correct judgements.
He correctly deduced that the Minks were lying and protected Raizo. He held enough faith in Kanjuro’s tip off to relentlessly attack nonstop for days, past the point where any other man would begin to doubt the reliability of their info (The Mink race practically got genocided just to protect a single man. Who could possibly believe that?).
He knew how important Doflamingo was, so he dropped his Raizo mission with zero hesitation (despite having been at it for days and having effectively won. All he had to do at that point was search the island) and changed priority to attack the Marine fleet.
He suspected the Minks were still surviving on Zou and may have recovered but didn’t have time/physical health to pick a fight, so decided to wreck the island instead. Which at the time seemed like a safe idea considering Zou didn’t seem to be capable of attacking.
Despite his supposedly brutish personality, he shows fair respect to competent people above and beneath him. He took advice from Hawkins and his subordinates in trying to manage Kaido’s drunkenness when we see him in Wano. Even sat down to listen patiently to Hawkins’s suggestion, despite otherwise greatly outranking him. And when he reported to King and Queen about his failure to rescue Doflamingo, he formally apologized even as King and Queen reprimanded him (and insulted each other).
Jack loves violence, but knows how to be pragmatic. When Kaido showed up drunk and started wrecking Kuri, Jack was horrified. But despite his subordinates saying they should run, Jack opted to figure out a way to stop Kaido. His reasoning being that the citizens of Kuri are an important asset as workers to the crew’s weapon factories, and that Kaido’s drunken rampage would destroy them for no reason.
When the raid started, he went straight for Kaido’s position while King and Queen busied themselves with the lower floors and samurai. He was the only member of the top brass to back up Kaido directly in the fight and took out nearly all the Sulong minks, leaving just the Scabbards. Kaido himself even praised him for that.
Even now, he quickly assessed the Scabbards and Momonosuke are a massive morale point for the enemy, and both are in vulnerable positions, and so is moving in to capitalize on that.
Jack always fails every time, but he at least tries to make a tactically sound and motivated decision. Meanwhile Queen merrily wrecks his own advantages and creates problems for himself out of his own sheer stupidity. Jack just has a tendency to pick fights with enemies that are out of his league (a Marine fleet led by an Admiral, an island-sized elephant, and an army of Sulong led by the Scabbards), yet despite getting repeatedly wrecked, the man recovers in relatively short time and is back on the field soon after.
