comparar 2 arrays, si son diferentes sincronizar ambas listas para angular

public static void Main()
{
    var aList = new List<int> { 4, 1, 6, 8, 3 };
    var bList = new List<int> { 0, 2, 5, 7, 9 };

    var result = new List<int>();

    var a = 0;
    var b = 0;

    while (a < aList.Count || b < bList.Count)
    {
        if (a < aList.Count)
        {
            result.Add(aList[a]);
            a++;
        }

        if (b < bList.Count)
        {
            result.Add(bList[b]);
            b++;
        }
    }

    foreach (var i in result)
    {
        Console.Write(i + " ");
    }
}
