That's like asking which is better - Chevy or Ford. You'll get answers both ways. As has been said, it may depend on what you want to tow.
As full-timers, we have traveled all over the country - several times. I can tell you at least 80 to 90% of all motorhomes towing vehicles are towing 4-down.
IMO, 4-down is better unles you absolutely, positively HAVE tow something that can't be towed 4-down, and which can't be modified with a lube pump or drive line disconnect.
One advantage to towing with a dolly is you can tow most vehicles without having to make any modification. Another is you may save a little wear of tires and other rotating parts on the toad, but you'll still have tires on the dolly to replace.
The big disadvantage to a dolly is finding someplace to put it when you stop to camp.
Although you may be able to save some money buying a used dolly, the cost of the dolly will more or less offset the cost of a tow bar, baseplate, auxiliary brake, and tow lights.
