python - The best way to implement a service layer in DRF

Question

I am going to implement a multi-threaded application using django rest framework and MVC (model-view-controller). Every new call to my application - is a new thread. I want to put business logic on a separate layer. I have two ideas how to do this

Idea number one:

class UserService:
    @staticmethod
    def create_user(user):
        # some business logic
    
    @staticmethod
    def update_user(user):
        # some business logic
    
    # another business methods

And the service call will look like this:

user_created = UserService.create_user(User("John", 19))

Idea number two:

class UserService:
    def __init__(self, **kwargs):
        # maybe some logic 
    
    def create_user(self, user):
        # some business logic

    def update_user(user):
        # some business logic

# another business methods

And the service call will look like this:

user_service = UserService()
user_created = user_service.create_user(User("John", 19))

Which implementation is best? In the first case we have static methods. In the second case we create a new object every time. What is the most correct way to implement this using a DRF and MVC?
