The Haven Tent is indeed a very comfortable sleep solution (notwithstanding the matress temperature rating failure). And it is the best dual solution, hammock plus tent, on the market.
On the con side, it takes more volume when packed. And takes more time to pack/set-up. Also, it sacrifices the traditional hammock comfort when the hammock and underquilt wrap around you on the sides and keep you warm/out of the wind. The Haven Tent is a much more “breezy” experience.
