Why is the best practice way to get all items from SPList(with query or without)

This is my ways :

  static void Main(string[] args)
    {
        try
        {
            using (SPSite mySite = new SPSite("http://sf-spsdev04/sites/gkk92"))
            {
                using (SPWeb myWeb = mySite.OpenWeb())
                {
                    SPList myList = myWeb.Lists["Employees"];

                    SPListItemCollection myItems = myList.GetItems();


                    //1st way
                    foreach (SPListItem item in myItems)
                    {
                        Console.WriteLine(item["Title"]);
                    }

                    //2nd way
                    foreach (SPListItem item in myList.GetItems())
                    {
                        Console.WriteLine(item["Title"]);
                    }

                    //3th way
                    foreach (SPListItem item in myWeb.Lists["Employees"].Items)
                    {
                        Console.WriteLine(item["Title"]);
                    }
                }
            }
        }
        catch(Exception ex)
        {
            throw new Exception(ex.ToString());
        }
