Sawtooth.
I have been using the same one since 2015 and it has held up for a lot of nights and some serious weather. There might now be a better option but I haven't found it yet. A bit heavy, but tremendously spacious, great footprint, nice tall entrance, good material, great zipper, simple pitch.
For a no holds barred lightweight 1P tent I think there are better options than the Supertarp. I have spent several nights in a Tarptent Protrail LI and can attest it handles weather very well. Lighter than a Supertarp and requires vastly fewer stakes.....though you can't run a stove in it.
