My experiences: Continental TKC80 - Very good performance in all conditions, but wear out very quickly (~2000 miles). Motoz Tractionator Rallz - Excellent traction off-road, acceptable performance on-road. Completely worn out after full TAT route (East to West). Experienced A LOT of cracking at the base of the knobs. Probably won't use again because of this. Dunlop Trailmax Mission - Excellent on the pavement and surprisingly great in most off-road conditions. Extremely long wear so far. Used on entire TAT (West to East) plus over 1000 more miles (mix of dirt and pavement) and still have over 50% tread remaining. They are quite heavy, and I am running tubes in them, but they should be ideal for a tubeless setup.
