Choose one of the two options, comparing them, the gains in the Pirate World are richer, but Su Xiao does not plan to enter the Pirate World in the near future.
The reason is simple, Su Xiao is not strong enough yet. His first Derivative World was the Pirate World, and entering the Pirate World that time actually had no impact on entering the Pirate World later.
But when Su Xiao entered the Pirate World the second time, he first cooperated with the CP Department and later killed several from the CP9 Department at Enies Lobby.
Forget about the CP Department's attitude, even the Navy Fleet Admiral Sengoku would explode with rage, the person responsible for 'protecting' Su Xiao was dispatched by him, nominally to protect but actually to monitor.
Su Xiao made quite a scene at Enies Lobby, which was like putting a pot of shit on Sengoku's head; Sengoku was sitting at home, and the pot fell from the sky, so Sengoku would not easily let Su Xiao go, nor would the CP Department.
