Since List<> is not indexed in any way, it has to go through all values to find a specific value. Therefore it doesn't make much of a difference compared to traversing the list via an enumerable (apart from the creation of a enumerable helper object instance).

That said, keep in mind that the Find function was created way earlier than the First extension method (Framework V2.0 vs. V3.5), and I doubt that they would have implemented Find if the List<> class had been implemented at the same time as the extension methods.
