Get ATs they said, you'll be fine...

Here is a Ford Raptor going sideways after backing out of his driveway, probably the stock KO2s, LOL:

Most ATs with good siping, even the hard rubber KO2 (snow on snow traction is best) will do fine on snow.
Add in icy conditions, and all ATs will suck, some much more than others.
I have had horrible experience on Ice with KO2s, and somewhat impressive (for an AT) on ice with some old Generals, Falken Wildpeaks, and the Toyo AT3s.
As a recovering ski bum, I used to drive mountain passes 50-60 times per winter, and the old BFG KO was the only tire that gave me no confidence on those ski days.
I am very impressed with the Falkens, and have them on 3 vehicles year round.
I put on the Toyo AT3son my 200 last year and drove through a few snow trips ( 1,200 miles round trip through mountain passes from WA, MT and UT and one early snow this year and while subjective, feel the Falkens do a bit better with winter traction but I thought the Toyos did well (they are suprisingly noisier than the Falkens but not bad).
I run Hakkas on my 200 in winter, so other than some early season and late season ski trips, and my one 1,200 trip, they sit in the garage in winter.
When it comes to icy conditions, ATs can be scary, and all it takes is a patch of black ice to change your life. For me the added safety of true winters is a no brainer.
So I agree that ATs can perform in snow, and I took them on easily 500 trips through snowy passes, I have learned that there is no substitute for a good winter tire. Studded Nokians fit the bill for me.
Edit:
I've said this in other threads, but the 3 peak snowflake symbol is a joke. The "baseline" tire is an outdated all season radial. Any AT will be able to accelerate at 10% better than the baseline (note they test acceleration, not stopping!). I would think any AT with siping would meet the minimum requirements if they were tested as they will hold a lot of snow for snow on snow traction.
The Rubber Manufacturers Association is making a lot of money providing a "certification" (tire manufacturer has to pay to certify every size they want to have the 3 peak symbol) that really provides very little data to consumers.
When a studded Nokian has the same symbol as a KO2, you know it isn't telling you much of anything. The rating should be based on a numerical system of at least 1-5 (1-10 would be better), where 1 is the current 3 peak minimum rating (10% greater than baseline tire), and moving up from there so consumers can see a true apples to apples comparison of each tire. I'd imagine no AT would get above a 3 or 4 on a 10 point scale, but it would give many of us the tools to make informed decisions, especially if we plan to run an AT all year round.
