Ice Driving! Which engine layout is best?

I used to think FWD was better but a couple years ago I had a 76 valiant 4dr beater.
Piled up a bunch of stuff in the trunk and did not have snow tires, jus 195 75 "Viva" tires.
I was very impressed with the traction, did not get stuck. Now I have a 95 caravan and it has not gotten stuck, however, it seems you have to be real careful about the back end coming around on you when you hit the brakes. Of course last year we had a ton of snow, luckily I had my 4x4 dodge P/U running at the time. I dont think I would have made it in some of the snow storms we had here without the 4x4. Christmas eve was just a crazy storm, I had to go out in it. Kinda an emergency for my neighbor cause his baby was sick and only one store in town open. He thought we were gonna get stuck bbut we didnt. You kinda get a sense of what your vehicle will and wont do in the snow if you pay attention to it. That is what keeps you out of trouble.
I have had many years of experience driving semi trucks in the snow. Now that is something everyone needs to experience.
