Which is the real question, isn't it... which is better for slick conditions, FWD or RWD? (no 4WD!) I'm partial to FWD because it's the type of car I always drive, BUT, if you think about it, there are three advantages to it:
1) The weight of the engine is on the drive wheels
2) The drive wheels can be directed
3) The driver gets feedback on steering AND traction through the wheel
