For me, the only real benefit of a tent is that you can share the set up with another person. I know some of us have come up with creative solutions. Side-by-side hanging, bunkbed hanging, etc; but for the most part when you build your hammock set up it's just for you. The intimacy a tent provides is the only thing I've ever missed after moving to a hammock.
Otherwise the benefits of the hammock far outweigh a tent in my opinion. If you go to something like tentforms.net you may get a different set of opinions.
