A Few years ago we used A-1 paving to blacktop our driveway. Their estimate was the lowest and since the project was pretty expensive to begin with, we decided to go with A-1.
I was satisfied with the work that they did, but not thrilled. Some of the edges were a bit sloppy and some settling has occurred in a few places.
I did complain about some of the settling and to their credit they did return the next year to patch a small area.
With a few exceptions the driveway still looks good 5 years later. If price is your biggest concern, I would recommend them, but if you want top quality over price I would look elsewhere.
