Concrete Versus Black Top?

[Indian113]

Getting Bids on a New shop and garage combo to park my Motorhome in. I will also end up with a 24x48 ft shop just for my toys so I will have room to actually tear something down and WALK around it! I am putting in a 6 inch thick concrete floor so I can handle weight of my Class A and put a Auto Lift in shop area. My question is has anybody used black top for driveways or would I be better off to just go ahead and pour concrete all the way. I'm looking at atleast 70 ft by 12 ft driveway and a 15 x 40 area in front of Garage. I wonder if prices are comparable?
