I will assume that female me will have a similar genetic makeup (so basically me as I am with more feminine facial features and a female body).
If I had the option then I will take it. 100%. I absolutely despise having a male body, it's a constant uphill battle to make myself look nice. Even if you don't take "looking nice" into account, having facial hair and masculine proportions just disgusts me (though I'd look decent with a beard, I painted myself a beard with eyeliner and I looked like a blonde Conchita).
Beyond appearance, I just want to be treated like a girl. For many reasons, some of which are possibly sexist (but in a lighthearted kinda way, nothing too cynical) but most just relate to how I am as a person. In a male body, I am expected to be something that I am not. Of course I'd have unreasonable expectations as a female too, but I'm at least closer to reaching them. Though male or female, my attitude will always be "go away I do what I want".
I think the biggest reason is just that I want a woman to love me as a woman. Not because it's "hotter" that way but because it just feels more right. When girls have been affectionate with me there's this nice absence of masculinity that makes me feel at ease. Does that make sense?
(Though uhhh... ideally, if I could be anything I'd have a female body with male reproductive organs... not as a kink but just because it's what I'm used to and if I had more delicate features I'd be on the way to having a body like that anyway.)
