I have not tried any hammocks that are intended for backpacking, but rather I have tried numerous patio type hammocks. I have not been able to get comfortable with the inevitable bow in my spine. When I try rolling onto my side, it seems to put pressure on my knees.

On the other hand, I sleep very well in a Big Agnes Horse Thief mummy bag without a hood. I use an uninsulated air mattress for most weather. If the temperature gets much below 40F, I need to add some insulation.

Because it works and because I've never been able to get comfortable in any hammock, I haven't seen a reason to try camping in one.
