Half-viking, I'd say a lot of it is down to how friendly/expansive the two of you are in close quarters. The Cruxen are 120 wide at the door and IIRC taper a little, so that's not actually much space by some standards, but plenty by others; I think the best thing to do is seek out either a Crux or at least something with a similar size of inner and see how happy the two of you are in it. Obviously some people are fine, others will prefer to sacrifice something for a bit more room (the missus and I insist on at least 140 cm wide inners if it's anything more than an overnighter, for example, but we're fussy, don't like sleeping head to foot and prefer not to wake one another up accidentally).
While the 3 poles suggested aren't quite as bunker-class as the Cruxen they should still take anything likely to hit them. Where I'd go for the full 4 pole is if you're expecting to use the tent as a static base-camp for days or weeks as the snow loading aspect becomes a lot more important then. If you're moving house fairly regularly it would be less of an issue, and personally that's where i'd lean to the Jannu or the g2 ultra over the Crux.
If it's a lot of snow use maybe the Ultra Quasar not such a good call as there's a bit of a gap around the base of the fly so spindrift can blow in and it won't be so warm.
I used to assume tunnels weren't up to serious snow use... but then I discovered that the likes of the Nammatj are popular polar expedition tents and I had to revise my opinion somewhat! The Nammatj 2 is a little lighter than the Cruxen and comes in the same basic fabric but actually has slightly thicker/stronger poles and a tougher groundsheet. The inner is wider, but the back tapers away more than the Cruxen. If your adventures are primarily mobile (i.e., strike camp and move every day or two) this starts to look like an attractive option, though, especially as it's usually quicker to strike and pitch than a geo (aided by the all-in-one pitch feature that all Hillebergs share).
For home comforts in the way of extra space and/or a second entrance the Allak probably comfiest with a large porch and door each, but you'll lose a little in the way of strength (I'd still trust it though, and you can double pole it for extra security like all Hilleberg models).
I guess if you were happy with teh VE25 inner-first pitching doesn't bother you: I should declare an interest that it bothers me, so I tend to be biased against things that do it in my suggestions...
But back to the Crux, as long as you're happy in that size of inner it should hit the bases you're asking for very well.
