concrete ftw, driveway quality asphalt may be grossly disappointing.. be careful not to compare your favorite stretch of city avenue for reference
asphalt of that quality would be prohibitively expensive and still not as suitable for parking and standing equipment as concrete..
asphalt is flexible and will not stay flat and square like a good concrete slab for my taste..
to be certain, you should be able to get a couple of free quotes.. compare their recommendations, qualities, and warranties..
good luck!
