I've run both for 20k(+) miles a piece on different vehicles. I was very pleased with DuraTracs in slush/snow conditions. They're snowflake rated and almost as soft as dedicated snow tires like Bridgestone Blizzaks with tons of siping. The trade off (in my experience) is a very soft riding tire that wears relatively quickly (mine also started chunking from mild off-road driving around 25k). They did grab well off-road, but I wouldn't trust them to hold up to root/rock punctures on the trail.
My ST Maxxs (also a "commercial" tire) seem to be as good as DuraTracs in the snow and better off-road (granted, my DuraTracs were on a Tacoma and my Coopers are on a heavier SUV, so not apples to apples). However, they are heavy, stiffer (only E-rated), and they do get noisier than the DuraTracs did after 15k-20k.
That said, if OP is looking for help with snow driving to the slopes and not heavy off-road use, I'd agree that DuraTracs are probably the way to go simply because you can get them in the lighter C rating and there's no need for an E rated tire in that scenario.
Were are you at in Pittsburgh? I'm up in Wexford/Gibsonia.
