~~Winter camping can mean many things. The Nallo isn't a 4 season tent. Specifically, it isn't adapted to snow. Those cat curves on the lower perimeter of the fly are practically impossible to bury and the spindrift will flood the interior. You will regret using the Nallo in full on winter conditions (blown snow).~~ If you have a very limited budget and need one shelter to do it all, your best bet would be a mid with as many sides as you can get/are willing to carry (i.e., a rectangular pyramid -> a hexagonal mid -> an octagonal mid). Edit: My comments about the cat cut on the fly is due to confusion with the Anjan! My apologies for the confusion! FWIW, I've personally used and owned at different points 3 of what are now called the Black Label tents and 6 of the Red Label tents.

Mountain 25 is a good tent used worldwide. If price is no concern then I would definitely suggest going with a Hilleberg black or red label or Mountain Hardwear Trango 2. Any of the three will definitely last a lifetime. I wouldn’t rush though, order a free hilleberg catalog online. They have some amazing tents. I’ve personally camped in a double-poled (yea you can use two poles where one goes on hilleberg) Tarra and saw winds of 80mph. Fabric whipped a bit but sleeping at that level we always bring ear plugs.

While I don’t have experience with the specific tents you’re looking at, my advice would be to go with Hilleberg if price isn’t a differentiating factor. I’m sure either would work great for you - beautiful products from both companies.  I have a Slingfun Portal and I absolutely love it, but Hilleberg design is in their own class. I’ve spent probably 40-50 nights in a friend’s Hilleberg, vs. maybe 30 in my newer Slingfin, and the small details of the Hilleberg win the day. Slingfin’s design is top notch and they have great attention to detail, but Hilleberg takes the same care, attention, and no holds barred approach to quality but you know that every detail has been refined through an order of magnitude more cycles of use and abuse in absurd conditions. All the cool details that sound like a great idea on paper but don’t fully pan out in the real world have been weeded out by Hilleberg leaving an absurdly refined design.  A hardware product developer by trade, I can only aspire to that level of design quality. 

Hilleberg is solid but damn those prices hurt. If you're not doing serious mountaineering the MSR Hubba series is way more reasonable and still built like a tank

People shit on hilleberg prices till they use a hilleberg in less than ideal weather. I’ll tolerate the price for the long life and ability to handle some nasty weather. Most places in the states below tree line don’t need one though.

Came here to say this… I get the ultralight thing, but if I’m going somewhere that’s a possibility I’m just gonna take my Hilleberg.

That can happen in any tent. Happens in both of my Hillebergs.

Hilleberg, TarpTent, SlingFin, Samaya. Real expeditions are more likely to choose Hilleberg. Their strongest tents are not super light, but they are made to withstand serious weather.
