I'm a Hennessy devotee, but recently someone pointed out the advantages of a Clark. It is a year or more before I will be considering a new hammock, but already I have been checking the options. The Clark appears to be larger with more pockets and features. On the downside the one I'm looking at is heavier.

The Hennessy's have that asymetrical feature, so I can sleep flat and the birthing entrance/exit that is really neat.

Is there anyone out there who has experience using both? Which one do you prefer and why?

I realize this is not exactly responsive, but if you're considering other options, I have been extremely satisfied with my setup, which consists of a kelty parabolic tarp and a lightweight parachute material hammock. I sandwich my sleeping pad between the two pieces of hammock fabric for insulation and the tarp is suspended separately. if I need bug protection, I can string up a 2 oz. mosquito net under the tarp. it's lighter and cheaper than both the option listed, though without handy storage bits, etc.
