That is my experience too. I had Quatracs installed in September, which replace my stock tires which were supposed to be LRR tires, and the Quatracs seem to be better, although it's hard to compare. We didn't have a 19/20 winter, while the 18/19 winter was more substantial.
@ProDigit: It's hard to predict what the mileage would be for you. Apart from speed driving behavior also has big impact. Having said that, it's hard to imagine a Mirage would not do better than a Fiesta.
Here you can find some charts about speed vs mileage. The charts don't cover 90 miles, but some cautious extrapolating gives 35mpg at 80, and 32 at 90.
A new Mirage might do a bit better, as the 2017 facelift has a bit better aerodynamics, which has most impact on high speeds.
If you insist on driving 80-90, you should have a test drive before considering a Mirage. It's not intended for that speed (although it can, top speed is around 105), and handling might be disappointing.
