It doesn't matter. Christmas Day is not influenced by the day of the week it is on. It always feels the same, no matter what day of the week it is on. So whether it is on a weekday or a weekend, there is no difference. So no day is best for Christmas Day to fall on.
Leap day does affect which day of the week Christmas falls on, but Christmas will always fall on the 25th. Hope this answered your question!
