Due to some serious back issues from a rock-climbing accident, the only way I get a good night's sleep out in the woods is in my hammock. I have a big enough tarp pitched over it to give me some good shelter, and I can pull the sides down to block the wind.
With a hammock you do need to deal with insulation that goes UNDER you. I am fine with a therm-a-rest pad, but many people use under-quilts that cost a few hundred bucks.
It sets up VERY quickly, and is much more comfortable than being on the ground.
