I have the UXV 450i and my brother has the Arctic Cat badged version of the 700. there is no place he can go that I can't, but putting the shoe on the other foot, there are places I can go that he can't, like the in the back of a log bed pickup truck.
If you browse around here, you will see pics of me pulling my 1000lb "toe hoe" or a 1000lb load of firewood in my Otter sled. The 700 might be able to go 2 or 3 mph faster, and it is probably a little thirstier
