Comment by @liamcary:

The last overload that takes a List as a parameter allows you to cache and re-use a list, whereas the overloads that return an array will allocate memory for a new array each time you call them.
The List overload will only allocate memory if the capacity of the list is smaller than the amount of items that the method needs to return. In that case the list will have to expand, but at least you can keep re-using that expanded list in future calls.
