To me, it's Yule, although I do enjoy the Christmas story. I prefer the quieter marking of the winter solstice to the conventional obligations (and, let's face it, bloody hard work) involved in Christmas. Ostara/Easter has none of those obligations attached, and happens at a lighter, brighter, time of year, making it my favourite holiday bar none.
Something about Christmas also amplifies loss, and I miss my Mum in December almost more than any other time. It does provide a welcome break from work in the middle of winter to regroup. But most of it's nicked from the pagans, including, in some Scandinavian traditions, the association between the Santa figure and the god Odin. As Odin was viewed as the Green Man, depictions of him in that tradition show him looking pretty similar to Santa but garbed in green rather than red.
It's so interesting, when reading about old cultures, religions and traditions, to see how many of them overlap and intersect. The idea of the virgin birth in old Egyptian myth, and the connection between Mary as goddess and Brighid, the Celtic goddess of healing, light and life, show how these stories come into being and intersect throughout many cultures.
There is not one prescribed meaning to anything.
