It depends on your proportions. I know there are TE'ers with "men's" bikes who are perfectly comfortable. If, however, you have relatively long legs and a relatively short torso and arms, you'll probably find WSD bikes more comfortable.
I'm one of those people who needs a WSD bike. I've ridden the unisex equivalent of my bike, just a few years older. That hurt. Your mileage may vary. Take 'em both for test rides. That'll give you your answer. Just don't try to convince yourself a bike fits or doesn't based on its looks.
Of course, I hear you on the colors and designs. Eek. I want a little aggression in my bike. My Giant does have a teeny swirly thing on it, but it's easily overlooked.
