I play both, and my rosters are often about 50/50.
Although that can come and bite you in the butt... My prefered race/gender combo in World of Warcraft is female tauren, mostly because they look awesome in heavy plate. But since they're not exactly the big bimbo-combo, quite a few people tend to assume anyone playing one is a lass for realz, which can lead to some awkwardness...
On of the atractions of this is that I do like to break the stereotypes sometime. The mild and kind female warrior with a sixpac like cobblestones, the big, burly male thief and infiltrator, that sort of little breaks from the routine.
