Naomi can be considered sassy and fierce, which she definitely is, there's no doubt about that, but sometimes she's just flat out rude. There's no need to insult and degrade people, and just cause you're Naomi, no one can fight back without fearing she's gonna throw a cell phone or something at them!
She's the kind of person you'd wish to be only on her good side
Karolina I think is sweet, but I find her kind of boring, and Coco.. I just love her. If I was on the show, I'd definitely want to be on her team
