My favorite was always the Antique Collection bottles, but after receiving the Michters bottles I like them the best. They have the same thick glass bottom (which is something I really like) as the Antique bottles, but they have a little more shape to them. I think, based on a pic I saw on the net, this bottle was also used for a bottling called Stone Castle. I also love the bottle that was used for the Wild Turkey 17 year, but since it was used for only that bottling I'll call it my 2nd favorite.
