I'll put another mark in the hammock column. Although I don't really have an aversion to snakes, I hate bugs of all sorts, especially spiders. Being up off the ground with mosquito netting eliminates unwanted visits from creepy crawlies. In addition to that, roots, rocks, non-level terrian and ground moisture are non-issues with a hammock. There's no way I could go back to sleeping on the ground. My setup - hammock with attached netting and sil-nylon rainfly - weighs in right at 3 pounds.
