I think that the answer to this question is going to be dependent on what you, as the reader, feel about them. Fitzgerald includes enough in it to help the reader form an impression. Tom's description and his manner in the chapter represents someone that is fairly full of himself, and someone that would prove to be difficult to embrace as a character. The "unrestfully" description of Tom represents someone who lacks loyalty and a sense of solidity that allows contentment to transpire. Daisy is shown to be something more than ornamental, but not much. It happens early on that one recognizes that material wealth and convenience goes very far in explaining their relationship. When informed of Tom's affair, Nick believes that Daisy should escape. The reality is she doesn't and the evidence to prove this is all around him and in what he sees. It is in this realm that a characterization of Daisy is formed, a condition that shows her to be attracted to the material life. The lack of emotion between them is something to be noted: "...when Daisy mentions Pammy, their daughter, Tom hovers 'restlessly about the room.” I think that these items can help form an opinion about Tom and Daisy.
