Why preserve the Commencement Bay escort carriers?

Should the United States retire converted escort carriers but retain the Commencement Bay class?

Yes: Commencement Bay was the mature purpose-built end of American escort-carrier development and a better ship than the emergency conversions.

The Commencement Bay class is a strong candidate to retain while improvised or converted escort carriers are retired. Although based on a T3 tanker design, it was a refined purpose-built escort-carrier development of the Sangamon lineage. The United States planned 35 and completed 19, making the class the final and most mature American example of the type. Its specialized hull was better suited to the role than the many emergency wartime conversions that shared its designation.
