Real lilies need to have their roots established in the ground going into winter, that's why you wait for the foliage to die down naturally with them...it's when they are building up energy reserves for next year's flowering.
Daylilies can probably be planted whenever, but you still need to keep them from drying out...and a plant is always going to do better with an established root system, so in the ground sooner than later is good.
