This is something that you will have to test for yourself and decide what is best for you. I don't know of anybody that uses a water pan filled with water in the UDS, but I am sure there are a few around. Most either use nothing or some sort of diffuser to even the heat across the cooking grate.
The reason I don't use a water pan is that on longer burns, which is most of my cooks 8+ hours) the water would evaporate and the temp would spike. One of the beauties of the UDS is simplicity without needing to do much once you get the fire going.
