OK, I'll kick this off by recommending the Outwell Minnesota 4.
link
Pros:
it stood up to lashing gales and torrential rain without a single leak
has SIG, and you can turn the 2 bedrooms into 1 big one for cosying up
is easily big enough for 4 of us, but not too enormous for a weekend/festival - (we also have a Montana 6 which would take for a week's trip.)
easy for 6'2" DH to stand up in
has windows on 3 sides so can be very light.
Cons:
the poles are heavy (which is probably what makes it strong).
needs 2 people to put it up.
Please add your own recommendations!
