I tried one back to back with my now pretty old SK650 and a new SK650. The Vermeer was way more money and despite the fact that they said it was the same ground speed as the Ditch Witch, it was not. It was marginally slower in forward and only half the speed in reverse. So I sent it back. Interestingly, my old machine with 1200 hours was the fastest and had the most power of the three.
