Awake() is particularly useful in situations where you need to ensure that certain initialization logic takes place before other scripts and components operate, especially if they rely on the data or configuration set in the Awake() function. This is crucial for maintaining the integrity of game state and behavior before any other interactions or updates occur, which is what makes it a preferred function for early script execution.

On the other hand, Start() is called just before the first frame update after all Awake() calls have been made, thus making it suitable for initialization that depends on other components being set up first. Update() is called once per frame and is used for processing logic related to gameplay that needs continuous monitoring, while OnEnable() is called when the object becomes enabled and active but can occur after
