Eh, not sure what is my answer here, so didn't vote at all. It really depends of everything.
If there is a character creation, then it might be a thing as simple as which gender has more nice looking tattoos, for example. If I play a game that feels somewhat "manly", I probably prefer male. Sometimes it's just a matter of which ever happened to be first visible in character creation. Sometimes other voice sounds ridiculous and I choose the other because of that. Sometimes in multiplayers with friends I choose my own gender, sometimes the other on purpose if playing with strangers.
Let's just say I choose my character's gender based on the current mood, whatever it happens to be at that time I don't have a favorite. If I play the game several times, I think I usually try to use both.
