Two of them had a different type of brussels sprouts on each that really stood out, especially the one of them that also had butternut squash, green bean casserole (made with goat cheese), chestnut stuffing and cheesy cauliflower (those being our family's leftovers). One couple always brings their leftover spinach and cheese balls and the pie made with those is always amazing; this year I believe there was something with pancetta on that one, too. I actually missed that pie entirely this year because it got wiped out while I was cooking the next pie and Mrs. 8893 forgot to save me a piece, but the crowd raved about it.
I am generally far more of a savory than sweet fan, but one neighbor always brings her maple pecan mashed sweet potatoes, and my favorite pie always ends up being one made with them. I think it may be the contrast with all the other savory pies that attracts me to it. In any event, this year it also had some good ol' canned cranberry sauce, good stuffing and the usual turkey and gravy, which find their way in some form on every pie.
