This one is a close one to me but I think Hitgirl takes this one mostly because of her speed, intellect, and she can pretty much hold her own against Elle.
While it may be true that Rick does have manners but to me he doesn’t quite fit in Morticia type in terms of dark atmosphere and creepy ness (he has been in a more light and action) style but Conan has shown to get along with dark type women before (like Belit who has the same style as Morticia) and giving good impression even though he’s a Barbarian he still has respectful to women if they are not a threat to him (I read a lot of the Conan stories and comics) so I can see him getting along with her in a dark style romance story.
