It's still one of the less busy times at Disney. You have to keep in mind that "less busy" now is not what it was ten years ago, as attendance in general has gone up across the board. But relative to the super-busy times like Christmas week and July 4, it's very doable. We've always found the lines to be reasonable, with the usual headliner exceptions, especially in the mornings. You get to enjoy all the Christmas decorations and events without the Christmas week crowds. I still rate it as one of the best times to go, but you still have to do some planning to minimize your wait time.
