I've had a nu way on my list for a while now but after finally doing some legit cold camping, I'm sticking to the Mr. Buddy. I have an Arctic Oven 10 so my results may be different than other tents. We had it out a couple weeks ago for two nights. Highs were around -5 and lows were probably -11 and wind was about 20 gusting 35. We had the Mr. Buddy on low the whole time and it probably averaged 45-50 in the tent. Inside of the tent was bone dry. All moisture was pushed through the liner and was a probably 1/16-1/8 sheet of ice on the inside fly by the end of the trip. Even when I use it in the fall and all summer I feel like it pushes all the moisture through the liner and my clothes have no problem drying out. The friend I was with has a 12x18 that he took Bison hunting two winters ago and air temp averaged close to -20 and got much colder at night. He used wood on that trip and talks about how much of a nightmare it was. You can see in the pics how much ice was on the fly when half it started melting while cooking and the second picture is of how thick the ice was after we finished the trip and pulled the fly off.
