I have been using and enjoying a Naturehike Star River 2 for a couple of years, which is very similar to the Mongar. Think it is based off of one of the Big Agnes designs in this case. 2 doors and vestibules makes all the difference to me when sharing, no crawling over each other and space for both people to stash gear. I find the Cloud Up 2 a little tight, and if I’m splitting the load between two people it doesn’t feel worth the weight saved.
Mine has stood up to some decent wind and rain in the Cederberg, but I don’t frequent the berg, so got nothing to contribute there
The Helios would be the more robust 2 man option I know of, but heavier and less flexible.
And if you are looking 3 man then it would probably be the Hiby. Which is about the same weight as the Helio with the benefit of a substantial vestibule for a chunk more money.
If you or partner happens to be tall I would check the dimensions on all of those Find it crazy how tent manufacturers are very determined to believe people over 6ft don’t exist.
