You should also consider how you clear snow and how that may impact you decision. I use a combination of 3PH snowblower and ATV plow on mine.

I ended up using a 4" layer of 2" limestone as a base then went over that with another 3" layer of 3/4" with fines. The surface is VERY hard and provided it's sloped properly the water runs off very well.
