Our thinking has also changed. We used to prefer late seating but we are not nightowls, and we found that while we weren't rushed to get ready for dinner, we were really just walking around in anticipation of dinner, eating it, and then heading back to the cabin and crashing.
Early works better for us. We are never late back to the ship anyway, and now we can get dinner out of the way, have the whole evening to do stuff, and by then have made some room in our gullets for a midnight snack. For us early is a much better plan.
