If you're a seasoned WRX-owner, focused on manual performance for under $50K, why wouldn't you just get an STi for less than $40K (and, if you have the full $50K, use the extra ~$10K on tuning upgrades that will blow any stock car, twice its value, off the road?) Plus, the STi handles great in winter. In this regard, good luck, with any peoples' car in the snow (presuming it even starts (a related problem), regardless of gearbox.
I gave-up on VW/Audi's two decades ago given their almost inexplicable inability to adequately perform in even, rudimentary, upstate-NY winter conditions (when my father's classic '63 Corvette split-window coupe was able to make it out of the garage and up the driveway, and my brand-new GTI couldn't, it was obvious to me that even ancient American engineering was superior to that of the modern German when it came to practical reliability--God Bless America!).
There's a reason why everyone living north of NYC has long abandoned VW/Audi as viable means of winter transportation, first, in favor of Saabs and Volvos and more recently, in preference of Subarus and their knock-offs. In addition to other failings, VW products suck in the snow. If you don't have to drive in snow, don't worry. If you do, take-out something else during a bad weather test-drive. You'll switch, immediately.
So you are basing your information, and recommendation, on personal data from 2 decades ago? Things have changed...a lot. The new (last 10 years) Audi AWD vehicles are absolute beasts in the snow. My A6 can go through anything...I barely even slow down in the snow anymore. If anything, they have made me a huge danger on the road when I drive any other vehicle.
Obviously Subaru's are everywhere in upstate NY, and are extremely good in the snow. I would argue at least part of the equation is economics though.
