I would say FWD is more "forgiving" in snow but RWD is more "fun".
RWD vehicles don't suffer "heavy-right-foot syndrome" well. You can of course induce over steer in a RWD car easier on pavement and it only gets easier when the conditions are slick. FWD vehicles want to under steer or "push" and that can be fixed with an already natural human reaction of lifting off the throttle and giving more lock into the path of travel. It can sometimes be hard to get them to turn in at all under speed hence the "Scandanavian Flick" or "pendulum turn". (You're using the movement or roll of the vehicle one way to make it easier for that body "momentum" to sway the other way and "roll" the car into a turn. It really does work although in short wheelbase FWD cars it can be spooky. Colin McRae and Auri Vantenen (?) were masters at it!
I'm with Kennith - RWD is more fun!
