Oversteer (RWD without enough traction) and understeer (FWD without enough traction) are two sides of the same coin.
Personally I'd rather have oversteer, which is easily compensated for (a bit of steering and let off the throttle), but doesn't impact your path around the corner. It's also quite fun.
Understeer on the other hand does impact your path around the corner, the car plows straight ahead as you ask too much of it. Additionally the threshold for understeer is lower since it's the front tires trying to handle acceleration and steering. So a RWD has more traction at a given speed than FWD.
Keep in mind that the that RWD in terrible in the snow comes from things like empty pick up trucks (no weight on the rear wheels) or old American sedans and sports cars that had large engines in the front and not much weight out back. Generally even with a perfect 50/50 weight distribution that the RWD is going to have the advantage.
If you're used to understeer (FWD loss of traction), then for safety reasons, you should stick to understeer. If you're used to oversteer, then stick with oversteer.
Its not like it snows every day. Your opportunities to practice loss of traction are few and far in between.
Dunno, it's not rocket science. Sure if it snows a few times a year, ignore it.
But if it snows often there's a simple choice. Do you want to lose the ability to accelerate (oversteer), or do you want to lose the ability to accelerate and steer (understeer)?
Even a single hour in an abandoned parking lot should get you familiar with either, and it's quite instructive to spend significant time over the threshold of sliding to help prepare you for the occasional surprise on real roads.
