Should I stay friends with my friends?

My friends (two) are not what you would call the nicest people. They are okay to each other (not great but okay) but are worse to me. They often insult me and say generally hurtful things (call me fat, say I’m stupid, say I have no life, call me a whiny b**ch, all sorts of pleasant things), as well as hitting me (got hit in the hear repeatedly with a balled up sweatshirt and had a headache for the rest of the day), scratching me (I have scars of my wrists from like two years ago from one of them) and stomping on my feet (which hurts a lot like wow).
The way I said this, it sounds like they are abusive, but they’re not. We fight (when they hurt me I hurt them back (but I don’t think I’m as harsh (but maybe I’m biased (but I’m pretty sure they’re worse)))), and I want to never have to see them again, but then like five minutes later they’re my best friends, they treat me great, I love them to death, and don’t know what I would do without them.
So basically, should I stay with them? Should I deal with the bad stuff to have the good, or should I give up the good to avoid the bad?
I’ve told of the bad things they do more than the good, so it sounds like they’re terrible people, but they’re really not. Nevertheless, you shouldn’t want to cry after eating lunch with your best friends, right?
So- stay friends, or platonically break up? Because I really have to clue what to do.
