what key differences exist between Nick and Tom also between Jordan and Daisy?

Daisy is gorgeous; Jordan is attractive. Daisy and Jordan are both shallow women, but Jordan tops off her shallowness with manipulation. Daisy is sentimental, romantic; Jordan simply wants what she can get out of a relationship..... totally unsentimental.

To Jill-

Thank you so much for all of your help.
