What is your good trail/pure ugly riding ratio gonna be? I just ran 5000kms on a set of Mud Bugs, and have about 200kms on a set of Interco Swamp Lites. The Bugs clean better in the sticky mud, but are much rougher when riding roads or hard trails. In the real loose watery muskeg the Swamp Lites seem to float better and are 100x smoother on the roads/trails. I'd say that for a multi-purpose tire I'd go with the ITP Mud Lites, or the Interco Swamp Lites. For sticky mud; Mud Bugs or Gators. For the pure ugly; Mudzillas, Vampires, etc.
