Flat tow, much easier and quicker.
Here's an extreme example. In CA, went to pull into a fuel station, but couldn't seen the canopy over the fuel pumps as we came down the street do to the the palm tree's. Turned in, and realized the canopy was too low to get the DP under it. The DP was just off of the road, but the Jeep was well out in traffic still.
It was 5:00PM on a work day and traffic built up right on the tail of the Jeep so we couldn't have backed up if we could have with the toad on. I hopped out of the DP, unhooked the Jeep in about a minute, forced some cars backwards behind me, and drove the Jeep around to the back of the fuel station. Then jacked the DP around some to miss the canopy.
I never could have got out of that situation nearly so easy if my toad had been on a dolly or trailer.
