A clear advantage of Kiwi drive over Holonomic that Sanddrag didn't mention is that the traction on each wheel isn't thrown off by slightly varying terrain.

It was mentioned with the holonomic that when one wheel would get up on the loading zone triangles it would throw off their traction on the wheels and make control a little shaky. With the Kiwi its like the difference between a four legged object and a tripod - the four legged chair/table or whatever will teeter if not on a flat surface, whereas the tripod doesn't care.
