I tow 4 down for the above reasons, but if I had a car that I absolutely loved that could only be dolly towed, I'd have a dolly. If it could only be trailered, I'd have a trailer. As it is, I paid for the extra hardware needed to tow a car that we love 4 down because I felt the convenience was worth it. Not all non-4 down towable cars have that option though. As it is, the extra hardware cost less than a good dolly or trailer anyway...
