There isn't much to say, given how little we've seen of them in the series. I guess from the onset, they're your idealized "good pirates." The type who prefer partying than pillaging.
Their crew makeup is also tailored similarly to the Roger Pirates and Strawhat Pirates. Valuing quality crewmembers who each bring something unique and crucial to the crew's success. These aren't like other Emperor crews which have many disposable cannon fodder.
And that's great, but we've yet to explore the members that make the crew up. We're clearly building towards when the Strawhats meet with them as equals. However, that day is still not here.
Shanks is obviously the one we've the most insight on, but even he's relatively mysterious. His most stand out characteristics being he's a man who prefers peaceful resolutions, as well as a silly disposition, not unlike his late captain and Luffy.
All in all, I'm excited for when they are the focus, but for now, I'm mostly neutral to them.
