1) Nemo Gogo LE - To me, a "tent" that you can't sit up in is a glorified bivy. Nothing wrong with that, but depends on whether that feature is important to you.
2) Tarptent Moment - Good choice. Two things to watch for -- if you use an air pad (2.5" thickness), make sure you are happy with how the ends slope down. Some people don't mind at all while others find it "confining" with the sloping 'ceiling' coming down so close to their face. The second thing to watch is the relatively large, unsupported slope on both ends. May be suboptimal in heavy rain and light snow. This, of course, is solved with the optional longitudinal pole -- but that's an additional piece to bring, along with the weight. Still, even with the pole, this is a relatively lightweight shelter solution.
3) Big Sky Revolution 1P or Mirage 1P - I currently have the Mirage 2P (I crave space). The thing I really like about Big Sky is the way they stick to a "tried and true" design -- a simple dome that is eminently weather resistant -- and cut weight by using UL materials like silnylon. I also like the self-standing feature -- although most times, you can always find ways to set up non-self-standing tents as well. One thing to be careful: If you decide on B.S. -- email the company first to verify stock. If they have stock on hand, then you can count on fast delivery. If not, then it can be weeks and easily months of waiting!
