I use to use a Hennessy hammock but only in warm weather. In colder weather I would need to carry an underquilt and stuff. Got to be too much. Additionally, as others stated, I like having a tent to store my gear in and be able to spread out...especially on those rainy days. I have had days of torrential rain and wind and being stuck outside under a hammock tarp offers no protection from the wind and slowly things start getting damp. Either by rain coming in sideways or running down the ground under the tarp.
