Quatracs have half decent winter performance. I'd run them year-round in places that get occasional snow, and their wet and dry performance is considerably better than RE92. RE92s are lower RR, but they're lousy in wet and hazardous in snow. They're a Florida or California tire, or a tire you use when you also have dedicated winters. They do make the car feel more spritely, but for me, the choice isn't so clear-cut. Were they still available in our size, I'd probably run Michelin Energy Savers, which I found to be excellent. They were also a whole pound lighter than RE92s, and lasted twice as long.
For my next set, I'm thinking about trying Continental EcoContact 5's. Bridgestone also makes an Ecopia EP150 in our size. I also recently read a review that Prinx Xlab Comforts have taken the LRR crown, but not many people have run them yet. They're apparently a flagship Chinese tire, which makes many wary, but I figure China is plenty capable of building quality stuff if there is actually a demand for it.
