I've avoided hammocks, because I feel vulnerable with my butt hanging in the air. I don't feel comfortable with the idea of animals can readily be beneath my body while I'm sleeping. And there's the issue of finding appropriate support for the hammock, what happens if you're camping above treeline, or on frozen tundra?
I prefer either tents or tarps. Tents are especially useful in the winter, since you can create a micro-climate by using a small sheep herders stove. I've camped out in zero degrees weather in a pyramid shaped tent, dressed in sweat pants and a t-shirt, while a small stove kept in the interior temperatures comfortable. Using a pulk, it's possible to transport the tent, stove, and firewood without much effort.
If I'm backpacking, then either a solo tent or a tarp. Typically, I carry a bivy sack to cover my sleeping bag, so i don't have to be concerned about moisture issues. Some of the lightweight tarps cost as much as a tent. If you're concerned about weight of equipment, and you have a large budget, try:
www.hyperlitemountaingear.com On my last hiking trip, two years ago, I used a tarp and the sleeping bag/bivy set-up, which worked fine for myself and my dog. The bivy bag has an insect net too, so insects aren't a problem. Using a tarp also gives me more room to protect equipment, prepare meals, etc. A tarp can be erected using hiking poles or a hiking stick for support.
I recently acquired a new tarp, which may be of interest. It's made by Arcadia Gear, and it seems to be well constructed, What's interesting, is that the material is waterproof and it has an integrated heat reflecting material on one side. So, theoretically, if properly pitched, it should have a very low thermal signature. Nice for avoiding thermal scopes or drones.
Summer sleeping, I use a lightweight down bag, again with a bivy sack, winter, either a military surplus sleeping system, or a LL Bean synthetic bag, rated to -30F with a bivy sack. We have loads of sleeping bags, with various temperature ratings. Thermarest sleeping pads are usually used when hiking. If I'm just vehicle camping or canoe camping, then I use a paco pad, which is like a thermarest on steroids.
As I've gotten older, I find that I place more value on sleep.
