Just saw your edit about the big mouth with a spigot. In my humble opinion, a spigot should only be on your bottling bucket, never in your fermentor. Too many nooks and crannies to sanitize, and places for leaks to turn up. The big mouth bubbler (without spigot) is my fermentor, and a bucket is also a good choice. Get a second bottling bucket with a spigot and rack into it with an autosiphon when you bottle/keg.
