Well, this is a very interesting question. You are looking at female characters created by two male modernist writers who are known for their misogyny and asking how they compare to the actual voices of women of the modernist milieu as exemplified by St. Vincent Millay and Marianne Moore.
Right away, I think about how Marianne Moore's voice is so complex and quirky, coming at the reader from so many odd angles and so vividly expressing a unique and often variegated worldview. In contrast, Chandler and O'Neill's female characters tend to be types, serving primarily as foils for their male protagonists.
