I use a Hennessy hammock for camping, it's really the lightest way to go.
Pros: Light, quick to set up, comfy as fuck once you get settled in. Keeps you off the ground where critters like to scurry.
Cons: You need to find a relatively ideal place to set up. If you're in the woods, chances are you can find a good spot. Even "two person" hammocks are not really for two people. If you fuck up your setup you may fall out of your trees.
Temperature control is not really a con. You have the same problems in a tent, and cold ground will suck the heat out of you faster than cold (still) air under a hammock. Wind though under your hammock will fuck you up - but all you need is a little know how to prevent that. Essentially, if it's cold you are building yourself a cocoon, which means a water and wind barrier ie garden variety tarp and some insulation, usually in the form of an underquilt. A hammock + underquilt + rainfly or tarp is still less bulky than a similar tent outlay. If you're very worried or delicate, you can use a pad in your hammock too, I recommend an inflatable one. You can bring a sleeping bag, but remember that your underquilt essentially makes the entire hammock a sleeping bag.
Honestly, there is a lot of shit you learn just by going and trying it once, but I haven't met anyone who doesn't prefer it to tents if there are sufficient things to hang from.
Pic related, steady downpour overnight, ground was moderately flooded when I woke up but I was dry because I was 3 feet in the air. A tent situation would have been much different.
