If you have a long torso and shortish legs, I would suggest the Mens first. Of course, try them out, and have the shop work with you on getting the size right. WSD bikes tend to have shorter top-tubes and possibly shorter stems, as the 'typical' woman has longer legs and a shorter torso than the typical male.
Remember, you need to be comfortable on the bike. The WSDs will probably make you more upright, try it and the mens before deciding. Between the two brands I would choose whichever felt better, and if that was a wash, whichever was the better value and had the better component spec.
