Great overview. One thing that I would mention is that with melting snow, the pot size tends to go up and the burn times increase. The additional weight and heat generation can determine what kind of base you may need to support your stove in the snow. If I use my Kovea Spider and a large pot, a large base plate is required.
Deliverable power also can become an issue. If I did a lot of winter camping (invertible stoves), I might choose the MSR WindPro or the Fire Maple Blade II over the Kovea Spider.
BTW, you mention the MSR WindBurner, you should mention the concern about CO emissions. Particularly if you talk about cooking inside your vestibule.
