Used an arctic tent once. Happier than hell that I did. We jumped into Utah as an OPFOR against a team that was supposed to rescue a POW. We had a static position at the NG camp outside of Salt Lake, can't remember the name, it was in the late 70s. Anyway, we jumped in and brought arctic tents because the weather report said very cold and no real snow until about halfway through the exercise. Got to the Site and most of the guys just crashed on site in their sleeping bags, the old giant chicken feather frost bite model with poncho and poncho liner. Myself and one other used a bit of time to set up our tents. Woke up the next morning to about two feet of snow. Went from blow hole to blow hole waking and guys as we made a fresh cup of coffee for each. Some mighty cold guys but all survived and all set up tents.
The only time I used them. Did use a GP medium once on weather warfare training at Canon Mountain though.
Have used poncho hooches in the woods in the winter. If we are set in a semi secure area for a base camp then we can set one up, if a patrol base then never. As was stated, ruck sack and lightly dozing.
