Face over body. Wouldn't want ugly for either.

As for men and women and 'hotness', I truly believe men should always try and go for a woman who's slightly less attractive than they are for a relationship (nothing matters if for a fling tbh). Obviously tough on about 80% of men, here, but having been with 'hot' women it's just a fucking nightmare, and it was way too much effort when they get peppered with attention and options everywhere they go. You might think you're equals in most areas of life, but then, bang, wake up call - she's beating them off every hour in person and in her DMs while you might get stared at or flirted with once or twice a day. Orbiters, friendzoners, lurkers...a whole army of attention under the platonic guise, before you even get on to strangers. Hot women really aren't worth the hassle.

It's ruthless as fuck, but a slightly less attractive woman makes the likelihood of cheating and evereything else infinitely smaller - so go for a pretty face and a nice, healthy, attractive, womanly body, without either being in the top 5% of beauty for either face or body. You can change the body easier than you can change the face as well.
