Haven't used it in a snow storm yet. If snow's expected, I'd take Hilleberg's 10mm pole (about 7.3 oz) instead of the regular pole (9mm and about 6.2 oz). If expecting very heavy wet snow, might take both and double-pole the tent.
Why superior? Can't compare the Akto to similar tents since I haven't used any similar tents. In deciding to purchase the Akto, I trusted reviews by other folks who had a lot of experience with the Akto. In particular, I read comments by Chris Townsend and others who (like him) have used the Akto in very windy stormy conditions (as in the Scottish Highlands, where I'd like to go sometime).
I was also impressed by the fact that the Akto had been around for years and withstood that test of time with few modifications in its design. The main design change that seemed to have occurred in all that time was addition of a vent over the door to help deal with condensation.
Although heavier (at 3 lbs) than more recent similar tents that I've read about, I believe the Akto is exceptionally well-made, and provides solid protection as a double-wall tent with very nice features for one person. Especially like the design for the vestibule and the inner tent with the space and flexibility afforded, although the single centered pole and extended ends have been criticized as a weakness when loaded with heavy wet snow.
Guess I'll just have to find out for myself one day how the Akto handles heavy snow when I use the heavier pole (or perhaps double-pole). Either way, figure I can also knock snow off before it gets out-of-hand. I can see that a snow load issue could/would arise if the Akto is pitched and then left unattended for a heavy snowstorm. However, I don't plan to use my Akto as a base camp for winter trips, or leave it unattended for a lengthy period.
I've gone on way too long. I'm certain that others have a lot more experience with the Akto and can provide a better evaluation — especially your question about comparing the Akto to other similar tents.

PS: The forecast here in the Willamette Valley is for a bit of snow the next night or so. If I get a chance, I'll pitch my Akto and see how it handles whatever comes. Since this is Oregon, the snow is likely to be wet & heavy even with just a few inches. Probably a good coat of ice, too.
