A well balanced 6wd will have better turning response/handling than a 8WD because it will have minimal wheel scrub forces on the outer wheels (due to there being very little weight on them). We find this to be a huge advantage and really helps with having an amazingly driven robot.
6wd also have fewer parts, which helps with weight and manufacturing.
