In my opinion, the Booths located in the Trading Plaza are the better option than trading. However, this may not be true for everyone, and it's essential to carefully consider your own needs and preferences before making a decision. The decision to sell or exchange pets is personal, and there is no one-size-fits-all answer. As I have already mentioned in the "Booths" section, you will basically have to decide on whether you want to get the currency or wish to get a particular pet. Once that decision is made, you can proceed with the preferred way.
