   Yamato is a must-have! Multiple female leads (but not drawn-out) + primarily multiple Devil Fruits (great development potential, satisfying readers' expectations) + protectors of the Luffy Pirates (not on the same ship, they have their own) + using Devil Fruits to create Dragon Ball elements (creative) + rich plot (with humorous moments) + undercover element (main character is a pirate, secondary character is a Marine) + all the crew members are new recruits (doesn't disrupt the original feel, I think it's great!) + Fast update speed (guaranteed).
