I love that Dean and Sam gained a sort of immortality through the people they helped, it's a wonderful gift after all they've done in life. That ending concept is fantastic as well - even more so that Death starts spreading these tales - that the brothers will come back to Earth if they are ever needed again. I really enjoyed Death's point of view, since we don't get it a lot, as he comes to understand the legends the Winchesters have become, why they are legends and why they deserve to be kept alive. Great fic.
