I run an Explorer Scout Group.
We have a selection of US The North Face hike tents, VE25's, MTN 24's WestWinds, Tadpoles etc.
We also have a selection of UK Terra Nova hike tents, Trisar, Quasar, Hyperspace.
They are all very good top of the range tents, over engineered, bomb proof, will stand up in anything, geodesic poles, light enough to carry in a rucksack or pannier, good in mud, rain and snow, winter and summer.
That said:
In terms of quality of build, I think TNF have the marginal edge over TN
In terms of weight when comparing like with like, then TN have the edge over TNF
There is a noticable difference in design. The TNF tents all have short fly's which if you are pitching in snow is vey good, but not so good when pitching in rain as water can run under the tent
The TN tents have the longer flys and so better in typical Northern European winter wether, ie rain and mud.
So in summary, if I was after a 2 man lightweight hike tent, with geodesic poles, suitable for year round hiking/cycle touring in Northern Europe I personally would buy something from the Terra Nova Quasar range. That said my second choice with the same spec would be someting from the Mountain 24 The North Face range. (1kg heavier)
