Personally I find my hair is just work if it's short. It wants washing every day, it sticks out, it looks messy unless I blow dry it, put gell on it etc. basically it becomes an attention seeking toddler.
If it's just below my shoulders I don't have to do anything with it, except get it trimed when it gets 4 inches below my shoulders and starts to split.
DD1 has proper long hair, it doesn't split
