What are the advantages and disadvantages of Oracle Bone Inscriptions?

I think I am an amateur. The advantage is that it is more vivid and concrete. For example, the car of a car, you see Oracle Bone Inscriptions drew something with two wheels, and you can definitely guess it is a car. I think the disadvantage is that some words are complicated and incomprehensible, and there are some words, such as a star with a star and Oracle Bone Inscriptions with three circles, but these three circles can also be said. There are too many words, such as Tian Tian, written in Oracle Bone Inscriptions. There are four boxes, six boxes, eight boxes, many boxes. If there are more than two similar items, it is difficult for Oracle Bone Inscriptions to express them. The above is my opinion. I'm an amateur and don't understand technical terms. Please forgive me.
