Fastest way to compare two lists

List<string> l1 = new List<string> {"Hello", "World","How","Are","You"};
List<string> l2 = new List<string> {"Hello","World","How","Are","You"};
Console.WriteLine(l1.SequenceEqual(l2));

public static bool CompareLists(List<int> l1, List<int> l2)
{
	if (l1 == l2) return true;
	if (l1.Count != l2.Count) return false;
	for (int i=0; i<l1.Count; i++)
		if (l1[i] != l2[i]) return false;
	return true;
}

public static CompareList<T>(IList<T> obj1, IList<T> obj2, Action<T,T> match)
{
   if (obj1.Count != obj2.Count) return false;
   for (int i = 0; i < obj1.Count; i++)
   {
     if (obj2[i] != null && !match(obj1[i], obj2[i]))
       return false;
   }
}

var testList = userInput.match(/[-|w]+/g)
        /*the above catches common errors:
         using dash or starting with a numeric*/
    listToUse = userInput.match(/[a-zA-Z]w*/g)

    if (listToUse.join(" ") != testList.join(" ")) {
                return "the lists don't match"
