Owners experiences sought

We’ve owned our AF 27-5L for over 2 years and have spent times in it winter camping with temps in the 20s. Haven’t owned any of the other two brands you mentioned. Ours has dual pane windows which I feel helps with along with the insulation to keep it cozy warm. The best part is we don’t look through condensation on the windows and have that damp feeling.
