I have a ten year old Tarptent Rainbow, still using it, still good as new.
I can't imagine any tent faster or easier to set up. (I've owned many...) It has exactly one pole. It isn't freestanding but with a grand total of six stakes, that's not an issue for me.
It's a complete bug-proof shelter, with floor tub, large front door and excellent ventilation. It's single-walled, so condensation is an occasional issue. It's not the driest (dryest?) tent I've ever used. But at 32 oz. carrying weight, it's about the lightest. It's the solo model, but very roomy.
