I toughed it out a few years in a bivy, it got old... I'm 6'6" and needed a tent with room. So that might be one requirement that you do not need to consider.
Since nobody I climbed with could stand my snoring like a freight train I bought a hilleberg soulo. Room enough for me, room enough for my stuff, and very lite considering how strong it is. I bit the bullet and paid full retail for it, worth every cent.
After the Soulo I got a Bibler Fitzroy to use as a 2 man tent. It is a very well built tent, but I need a vestibule. So... I sold the Fitzroy for a profit and scored a Hilleberg Allak for $400 on craigslist. It is roomy, lite as they come, and built like a brick shithouse.
Fully guyed out it stood up to winds 80mph sustained with no snow wall. Ya it was a rough night but it held up just fine. Taking it down was kind of rough, had to get 2 people from the hut to help us so it wouldn't blow away. I have heard the Allak can handle even higher winds. Somewhere I read that some dudes were in an allak on Shishapangma in winds 100mph sustained gusts to 120mph. But they had a snow wall. Other tents were shredding but the allak was unphased. The only drawback is the $$$. I hunted on craiglist twice a day before getting my allak cheap but they are out there.
Which makes me wonder... does anyone independently wind tunnel tents to test their various points of failure?
So... I needed a tent that was larger, light, and tough. Which narrowed it down to like 3 tents, 2 of them being Hillebergs. I am glad I am tall otherwise I probably would not shelled out the extra cash and never owned my awesome tents.
