Deanna Troi got my vote. Sure, 7 of 9 has the best body & many of the others have that "alien next door look," Deanna also has a power than can be very sensual
Jadzia Dax (Terry Farrell) will probably be my all-time favorite, but most of the women looked well.
Okay, Kes had a screwed haircut, but when that was changed, she looked not bad.
Janeway is probably a bit too old for someone like me
Seven of Nine didn`t look to well - she looks better without the "uniform".
(Oh, and Torres - if it wasn`t for her half-klingon "design" - but on the other hand...)
So, maybe, the true reason why nobody likes voyager is, because none of the women looked good enough (at least within mask & uniform)
