RigoletMan...
The 550 does not have anything even close to the same fuel mileage compared to the standard Series-III 600 in the Skandic WT 600, but admittedly, the SUV has a much better rear suspension and a better riding front suspension than the standard WT. Studding is not a common practice in your area, so that shouldn't really factor into your decision.
Seeing as you are not planning to cover large distances on too many trips, the fuel consumption of the SUV 550 may very well be fine. Both engines are common, proven and very reliable. You did mention that you will be using this sled to commute a lot during the Winter and to me that means that ride quality is going to be a very important factor. If that is a quality that is indeed very high on your list, the SUV wins hands down.
Thanks for the responses everyone, it has been a great help! After weighing all the positives and negatives, I've decided to go with the Skandic WT 600. Fuel economy was the biggest factor in my decision as the gas is so expensive in this neck of the woods, and I do go on weekend outings of a moderate distance. LabradorBoy is correct, studded tracks are not needed here, so that's not a factor at all. Also, I am fairly used to a stiff riding machine because I used to have one of the older Skandic SWT 550's...that thing was a tank!
BTW, any idea of how much better mileage you can get with the Series-III 600 than the 550? I really wasn't impressed with the fuel economy of the Skandic SWT 550 and Legend GT 550 I had...they were both gas guzzlers.
