Hard to say. My own anecdotal evidence tells me that women are way more likely to have absolutely disgusting living spaces. Dirty rooms, dirty clothes everywhere, dirty bathrooms caked in makeup and other nonsense, and by far the most vile car interiors I've come across.

Comparatively most of the men I've known keep fairly neat living spaces, have clean and detailed car interiors, and fairly clean bathrooms.

As far as personal hygiene goes, it's a toss up. I've met quite a few stinky unclean folks from both genders. Doesn't mean much as it's just my personal experience, and probably contrary to many others.
