I have a private method that is called from the constructor to instantiate a bunch of objects.

I can do it two ways.

    private Monster[,] createMonsters()
    {
        Monster[,] myMonsterArray = new Monster[8, 6];

        for (int i = 0; i < 8; i++)
        {
            myMonsterArray[0, i] = new Monster(SpriteFactory.getMonster1Sprite());
            myMonsterArray[1, i] = new Monster(SpriteFactory.getMonster2Sprite());
            myMonsterArray[2, i] = new Monster(SpriteFactory.getMonster3Sprite());
            myMonsterArray[3, i] = new Monster(SpriteFactory.getMonster1Sprite());
            myMonsterArray[4, i] = new Monster(SpriteFactory.getMonster2Sprite());
            myMonsterArray[5, i] = new Monster(SpriteFactory.getMonster3Sprite()); 
        }

        return myMonsterArray;
    }

called with

monsterArray = createMonsters();

or

    private void createMonsters()
    {
        monsterArray = new Monster[8, 6];

        for (int i = 0; i < 8; i++)
        {
            monsterArray[0, i] = new Monster(SpriteFactory.getMonster1Sprite());
            monsterArray[1, i] = new Monster(SpriteFactory.getMonster2Sprite());
            monsterArray[2, i] = new Monster(SpriteFactory.getMonster3Sprite());
            monsterArray[3, i] = new Monster(SpriteFactory.getMonster1Sprite());
            monsterArray[4, i] = new Monster(SpriteFactory.getMonster2Sprite());
            monsterArray[5, i] = new Monster(SpriteFactory.getMonster3Sprite()); 
        }

        
    }

called with

createMonsters();

Is either better or worse?
