Angie, I don't know about DaKine or North harnesses, but I have used both the mens and womans Liquid Force harnesses, and there is a HUGE different with padding and how the harness is actually cut and sits around your hips/ waist.
Have a look at male and female seat harnesses; there are a noticeable differences that range from adjustments around the hips, to padding and the height of the back support....

Don't focus to much on harnesses made for girls, i've personally never felt comfortable in anything with girly design features.
Seriously there is no difference between them, it's a gimmick.
