The girl on the Left is a big girl who has been losing weight and getting confident she can steal some other women's man. She has a target in mind, a smaller, skinny girl who has been gaining weight.

The girl in the Right has been getting heavier and losing stamina. She is madly in love with her boyfriend and is always willing to defend her relationship. Last time she beat her opponent but this time her rival is bigger and heavier than she is.

On a apartment catfight who wins?

The gal on the left looks significantly stronger and quite driven, even as the gal on the right is rather more attractive.
Based on these observations, I think the gal on the left will win and the gal on the right is cuter.
