We had a dolly for a few weeks, since it was part of the package we bought from a couple getting out of RVing. We towed our car home on it, 150 miles or so. It was a cheapie Stehl-Tow and didn't have brakes but it loaded easily and tracked well.
I don't think you'll dislike DRIVING with a Dolly, and I hear they'e easier on the car than four down. What you may not like is storing and parking the dolly. The best tip I've heard for dolly users, is add a hitch to the car. Then you can jockey the dolly around with the car if you need to.
