Obviously saying women from "X" are more beautiful than women from "Y" is a purely subjective statement. However there is an objective standard you can use (even if not "scientific") for the different states in the US - the number of Miss Americas per million population.
Here is a list of the number of Miss Americas by state per one million population. Seventeen states have not had one and are not on the list. Having lived in Mississippi, Alabama, and Georgia, those numbers are a fair representation of the relative frequency of drop dead gorgeous women I've seen in those states.

I went to Ole Miss (University of Mississippi), which produced three Miss Americas from that one school alone. Yes, Ole Miss girls are that beautiful.
