Adding a script from another game object

I am trying to add my script from a game object to another game object by trying to add component but I want it to have the same custom variables. I am wondering if I could add a component to the game object and change the variables to match the other game object. Here is my script so far…

GameObject cpuClone = Instantiate (Cpu, new Vector3 (6, -2, 0), Quaternion.identity) as GameObject;
			cpuClone.GetComponent<SpriteRenderer> ().sprite = player2;
			cpuClone.name = Cpu.name;

		
			PlayerCPU cpu = cpuClone.AddComponent<PlayerCPU>();
			cpu = transform.FindChild("Abilities").GetComponent<PlayerCPU>(); //Trying to have the same script as the gameobject Abilites

You need to set the value you need one by one.

I see 2 ways of doing it, the second is IMO better.
The first:

    cpuClone.AddComponent<PlayerCPU>();
    cpuScript = cpuClone.GetComponent<PlayerCPU>(); //cache it like this so you won't need multiple GetComponent
    cpuScript.value1 = Cpu.value1; 
    cpuScript.value1 = Cpu.value2; 
//etc...
//your values have to be public so it's not ideal

The second is having a function in your class like this:

public void GetValues(int _value1, string _value2) //as many parameters as values you need
{
    value1 = _value1;
    value2 = _value2;
    //etc...
}

Then call it after instantiating like this:

cpuClone.AddComponent<PlayerCPU>();
cpuClone.GetComponent<PlayerCPU>().GetValues(value1, value2) //etc...

I wonder why you need to add the component on run, wouldn’t it be better to have it in the prefab?
