You are right with the pro's you mention and that there is more head room and space in these tents, the Southern Cross isn't as roomy as the Hubba Hubba, they are also very easy to pitch. We haven't had any problems with poles, joints or hub except with the Hubba Hubba, if the wind changes, is strong (the tent should be pitched with the end into the wind) and hits the side of the tent it puts a lot of pressure on the middle pole which bends in. The Southern Cross's middle pole goes down to the ground so this is not an issue with that tent. Both tents still have noisy flapping in the wind. We haven't used the Southern Cross as much as the MSR; it was bought last winter and due to Covid restrictions or too bad weather we haven't been out in it this winter. I love the MSR tents we have despite the middle pole issue, we just try to make sure we pitch it with the end into the wind and are prepared to move it round a bit if the wind changes direction. Our Elixir and Hubba Hubba have both survived a good few batterings out on the fells! I'm not quite as fond of the Southern Cross because it isn't quite as roomy as the MSR but it is warmer and more sturdy so good for use in cold and windy conditions. Hope this helps!
