Main go-to right now is my SO-6 (full blown with two doors, bug netting, vents). I use an HPG Shepherd with that, if using a stove.
Second (and tested in four seasons, including alpine climbing) is an Exped Sirius Extreme. It was billed as a 3 man and could in a pinch, but it's really a 2 man with gear. I've recently modified it with a stove jack to use with my DIY "Steampunk" stove, as that it can be pitched fly only, thius floorless.
Also have a Bushcraft USA silnylon tarp that can be pitched in multiple configurations....very light and versatile. That will see some use during upcoming training in jungle environs.
Also have two hammocks that will see their first real test during the jungle training...one is a Mosquito Jungle Hammock, that comes with a catenary cut fly and integral bug netting. It can be used as a hammock, or as a ground-based 1 man shelter. Fast to put up and take down...very comfortable, so far.
The other hammock is one that I built out of a deconstructed Gander Mountain XL cot. I use a Catoma IBNS (Improved Bed Net System) that can be connected to the hammock. I can use the Bushcraft USA tarp above it for spacious coverage from weather. This one can also be used as a ground-based tent.
I have a couple bivy sacks that have gotten quite a bit of use over the years (Black Diamond and Outdoor Research), but there's really nothing to crow about with those, other than their being light and able to get out of weather.
Beyond that...a Eureka 5 man and Gander Mountain Grizzly Den 8 man....family tents that require carrying in with a truck. They get the most use for vehicle accessed campground stuff and the like.
