Each individual case needs to be considered separately.

At different stages of a professional career, the benefits of working as a traditional employee and as a freelancer will differ. At the very beginning, when an employee has little experience, it is more profitable for him to work for hire. But as soon as his level of expertise has grown and he can "sell" his time more expensively than the "labor market", it becomes more profitable for him to work as a freelancer. That is, the hourly rate will be higher and this gives flexibility in organizing your work processes (work exactly as much as you need).

There is nothing universal. Each type of work has its pros and cons. The choice should be made based on your capabilities and level of expertise, as well as a predisposition to a particular type of organization of work processes. Not everyone can be a successful freelancer and most prefer to work for hire, because there are advantages, such as the fact that all organizational issues are taken on by the employer (as well as issues related to taxes, health insurance, etc.).
