Min was always my favorite out of Rand's three. I just want to choke Elayne and though I like Aviendha I agree with @Almira ni'Caldazare in that I never understood their relationship.
For a husband, it's Perrin hands down. He's completely loyal and fiercely protective of those he loves. I think he's also the kind that you could talk to and would respect as a person.
As far as a wife goes I think Min is excellent, but I also like the lady who ran the tavern in Ebou Dar
