Is it better to be a clerk of a real estate company or a charging customer service of a property company?

I think it's better to be a real estate clerk. After all, real estate companies are bigger than property companies. As a clerk, you can understand the business process of the whole real estate company. If you do well, you can also do finance if you have the opportunity. The toll collectors of property companies are under great pressure and have many contacts with customers, which is very complicated.
