I've got a Kifaru Supertarp which is a like a door-less Paratipi. Adding an annex you get the front door/vestibule and a better stove location. Simple to pitch in various ways, light weight at 16oz, ton of room for one person. Best? Probably not but everything has trade offs.
I used a Scarp 1 for sleeping on an 8 day elk hunt this season and it works fine. I would not want to "hang out" in it for extended periods but that's why I bring a tarp for cooking, etc. Scarp is a floored shelter and can be set up free standing or not. Light and easy to pitch.
