I agree with most everything said so far but for me, I like the Clark best. First off weight does not really matter. I don't hike. I am either kayak/canoe camping or car camping. So most of the time my Clark is a base camp for a few days. All of the features like the pockets, weathershield and such are way more important to me than a few ounces. One thing not mention is the ability to move the net completely out of the way. I also like the fact that I can get in on either side. I am relatively short at 5'7" and lay asym in mine. Not as steeply as the BB but asym. I have heard many complain about the Clark tarp size but I find it plenty big enough to keep out the weather and it is certainly better than my stock tarps on the HH.
As for the BB it is comfortable but those side tie-outs get in my way, especially the one on the side you get in on. The net is also lower to the hammock and make sitting up with the net zipped harder. The shelf is ok but the pockets on the Clark hold way more and there is no chance of damaging the netting. I have a run in my net on the BB because something hung in the net as I was taking it out of the shelf.
