I'm feeling sorry for Sunncamp here. We have been very happy with our Sunncamp Vario 6 as it is a comfortable well made tent. I have not been tempted to abandon it for an Outwell despite how popular they are on here. I love how light and airy the living space is.
We bought our other tent the North Face Trailhead 6 as we wanted a smaller cosier tent for short trips/cold weather! I have to say the very high quality construction is apparent.
I don't think I could rate one above the other as they are so different. The North Face appears "higher quality" than the Sunncamp but the Sunncamp keeps us dry in torrential rain and has no functional problems- they have yet to be tested in really strong winds.
I have to admit if I was to start all over again I would probably try a Khyam quick erect but I'm not convinced the living space would be as pleasant as the Vario.

Other brands owned, Lichfield, Aztec, woolies cheap one, and eurohike?(I think? so long ago and very old now!) oh and one that clipped onto a gazebo which was complete waste of money!
