many of them have been there for years, same stories.
The new one this year is in Germany and they are a rock/punk band that, to me, was just way plain loud and didn't really incorporate enough Christmas storytelling traditions to their set, so I listened for about 5 minutes and left.
As to preference, my #1 is La Befana from Italy, followed by Las Posadas in Mexico, Sigrid and Juliennessen(sp?) in Norway, Father Christmas UK and Pere Noel in France
I also LOVE Joyful the gospel choir, they talk about Kwanzaa, Christmas and Hanukkah during their sets
