@Stratos If you're interested, I used the Chat with Lary function to ask this. Here's the response:

Static methods are useful when you want to perform an action that doesn't require an instance of the class. For example, if you have a utility class with a method that performs a calculation, you can make that method static so that you can call it without creating an instance of the class. This can be more efficient because you don't need to create an object just to perform a simple action. On the other hand, instance methods are useful when you need to maintain state across multiple method calls. For example, if you have a class that represents a user and you want to update their profile information, you would create an instance of the class and call its methods to update the information. This allows you to maintain the state of the user object across multiple method calls. In summary, static methods are useful when you don't need to maintain state across multiple method calls, while instance methods are useful when you do need to maintain state.

I thought this was an excellent explanation, to thumbs up Lary!
