Most of those sound like the same thing with different wording
But I guess he was a Warlord, which is my favourite group of characters, so I can't argue too much here.
I’d be curious to hear why you don’t like him. I mean, I do but I can critically analyze the character and see that the very traits that appealed to me also are what make him, in essence, a magical negro trope character but, as I share many of those characteristics/traits in my life and habits, I can relate to him on a personal level. I mean, it’s all in perspective. If there weren’t as much time and background given to the Sun Pirates, if he didn’t go back to help his crew in WCI, there would be larger issues with his character but as it is, he’s one of the better done versions of this trope in terms of being fleshed out and having balanced perspectives shown, in my opinion. After all, there are tons of tropes and metaphors in this series. There’s nothing new under the sun. Everything is based on something to some extent. Furthermore, he does serve his purpose, both in aiding the protagonists and in furthering the goals of his people—though one can argue the merits of trying to work within the system or trying to change the system itself—that comes down to whether you think the split in the initial Sun Pirates went down properly. As in what was the right answer back in the day? Or even with his beliefs, should he have done something about Arlong, etc? There’s a lot to unpack... is he a sellout for working for the government at all or is he The Spook Who Sat by the Door? Taking the cover of their information, services, privilege and skills in order to gain better advantages and training for his people in order to hide in plain site and start a revolution? Since the Warlords don’t necessarily get training but do get access to information and WG affiliates get more resources, etc, it’s hard to say... the same with the alliance with Big Mom. Who knows what he got out of these for sure. But he’s claimed that it’s for his people. With Whitebeard, I can believe that there was a genuine exchange in working with him but again, it’s relying on someone else.
I’ve gone on long enough. As I said, I’d love to hear your perspective especially since not many have a negative take on the character and it inspired me to think about it. ^_^
