Carl's Jr is one of the best but In N Out is best because its better and bigger for other people but i like both because there both good in different ways .There jucie and the fries are different because in carls there regular fries and In N Out theres animal fries.But i like them both no matter what but other people like one of them i don't know why because there both kinda the same but in different ways because there fats the other one doesn't so it depends if u want more fat or less fat.
