Have a Hilleberg Rogen that I'm really enjoying. I bought it primarily as a one person tent that would work in a pinch for 2. The dual vestibules and entrances sold me for the latter use. I've been self-quarantining the last 5 nights in it. Temps have been anywhere from around freezing at night to 12 this morning when I woke up.
I don't imagine it would do well in heavy snow, but I haven't had any condensation issues. Since it's the yellow lable it lets a bit more air flow through than the 4 season tents I think. I'm running a WM Antelope and have been staying toasty at night.
It withstood some pretty nasty winds (can't quantify the statement) last summer in an overnight trip in the Beartooths. I have since added guylines to the vestibules for added security. For some reason it doesn't come with them from the factory.
I don't have any other high-end tent experiences to compare it to, but I'm very happy with it.
