I roll out with a Shangri-la 1. I like it alot. It fits my needs just fine for a 4 season tent if you dont mind a single wall. I use tyvek for a ground sheet and pitch it really low if bad weather is threatening. Thats the only GoLite product I've ever used so I cant speak for the rest of there stuff. Unless your really counting ounces I'd go with the shelter that fits your needs the best.
