I have a mountainstar, it's an awesome tent. Its lighter, but it's not 4 season. The thing I like most is external pole system, you don't have to deal with a separate fly to try to pitch when windy or while it's raining. Quality and attention to detail is top notch. That said, If you want a 4 season, and don't mind the weight and the external fly, hard to go wrong with SG.
