I have a Warbonnet Blackbird and will say it is extremely comfortable. I used it form Pittsburgh to Washington DC and slept like a baby including through a storm with high winds that knocked large trees down across the trail. I was traveling to DC during Hurricane Irene.

With a hammock you will not be able to keep your gear inside. I placed a lightweight tarp under the hammock/rainfly and kept everything including the bike there. You also may have trouble at times finding a place to set it up, although most I talk to have always found a way. There are ways to use it as a tent but you will want a ground cloth, a large piece of tyvek works well for that. I have tied up to a picnic table and a post and even hung it in the pavilion of a YMCA in Cumberland, MD between the support pillars.

I like the tent for ease of finding places to set up, and the fact I can put my gear inside, but the hammock was much quicker to set up and tear down and worlds more comfortable. If the hammock is set up properly you will be able to lie basically flat and be very comfortable. You won't be tossing and turning because of the hard ground. You will need some type of insulation under you though since you won't have the ground underneath you. I used a sleep pad. If I every had to use the tent again I would miss the hammock.

The other upside is the small space it takes up and it's light weight. My hammock and rainfly come in at under 3 pounds total and fits easily in my rear Ortlieb along with my sleeping bag and other gear.

Spend some time on the hammock forums. I will say I am very happy I chose the Warbonnet Blackbird. It has been perfect. I got the double layer bottom so I put the pad between the layers. I love it.
