Yeah - I think any of the XGTs are good in all season format - the Pilot all seasons are supposed to be the hot ticket (think year round AND high performance - of course they cost as much as a set of winter tires and a set of summer tires. Honestly, I'd check TireRack's reviews for good all seasons - a good set of those should be more than enough for most cars.
The other thing is that snow tires wear FAST on dry pavement - which is what you get in DC 95% of winter. I don't think you'd get more than one winter out of a set of Blizzaks. All seasons can either be run on your rims or get a new set and keep reusing them until they get hard. (If I were thinking ahead, I would have bought a second set of wheels b/c the second time you swap them, you just bought some cheapos!  
Mine are sitting in the closet and will likely go back on the car before long b/c a) the RE's are shot; b) its winter; and c) I'm selling it and don't want the new owner to see what I've done to the tires on there <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>
