What is Harlan Ellison's best short fiction collection? My automatic answer is Deathbird Stories but Shatterday packs a wallop too. Two of his best short fiction works are here, "Jeffty is Five" and the title story yet there is not a filler piece to be found. All are quite impressive. I especially like his sad and reflective "All the Lies That Are my Life". Shatterday may surpass Deathbird Stories in that it encompasses a wider variety of emotions. Best Ellison collection? Call it a tie.
