I go with Enterprise
Jolene, Linda, Molly Brink, Abby Brammell, Kellie Waymire, Mary Mara, Golden Brooks
Worst = DS9. Ok DS9 had Dax the example of hotness, but the many of the rest were really obnoxious or dog ugly aliens like the Klingons. Nana's character, yeah she was very pretty but had the wrong attitude, she just weirded me out.
Leeta: very wow factor, fantastic boobs ! but was just too silly and her stupidity was so bad it kind of made Paris Hilton look like Albert Einstein
TOS had some great gals, but I think they were a bit too damsel in distress, too 60ish for me.
