This is my second 3R. I replaced my 14 year old only after my error in ruining one of the zippers with seam sealer (the tent is otherwise still great) and also to upgrade to the slightly lighter sil-nylon version instead of the urethane of yore.
I've used it in all 4 seasons.
With 2 people it real roomy. 3 is still nice. 4 people (2 short - going head to toe down the middle and 2 tall people) for 2 weeks during the winter and it was warm, a little tight and condensation was a slight issue.
It's held up all in all types of rain, wind (over 50 knots- they claim over 100 knot wind tolerance) and snow combos form Nepal, Peru, Australia, Mongolia, the Rockies, Olympics, Cascades, Adirondacks etc....
I highly recommend it. If you need something even bigger for 5-7 people check out the 5R.
They are expensive, but they last and weigh less than 4 lbs. I have the sidewindows and highly recommend them if you do any hot weather camping.
They have the easiest and quickest set up of any tent I have used. They offer lots of space inside.
Great tent if you are 7 ft tall.
I could go on.
The only downsides for me is that the "vestibules" are completely inside the tent- so cooking would be a no-go. Also, the tent has a long footprint so finding a suitable site is a little trickier.
These tents truely are light and spacious.
