What's there to research? I've driven both in all kinds of weather. The OBS has literally gotten stuck in my own unplowed driveway. It had regular all-season tires on it (BF Goodrich Traction TA) and still got stuck. My '87 has the same 205/60-15 Traction TAs on it and drove through the same driveway with no issues. The A6 I speak of had ultra-high perf. all season (AvonTech) and, yet again, no problem with the snow and ice. I am just speaking from experience, which, IMO, can me worth more than generic "research."
