For various reasons, current draw being one of them, our '00 bot used a 6 wheel drive. In this setup, all 6 wheels are powered, where the middle two wheels are set about a quarter of an inch lower then the 4 corner wheels. This allowed us good climibing on the ramp (the primary reason for the 6 wheels) but also reduced scrubbing drasticly when turning.

Of course, having 6 wheels is more expensive (wieght, build time, repairs) then 4, in our case it was a fabulous solution. If you plan on lifiting loads while acending inclines, it's perfect. Also, if you can get away with a two wheel drive, Why not? The bot turns faster and uses less current, the drive line is far more simple to make and repair, and probably most important, is lighter! Naturaly, using 6 or 2 wheel drives creates all sorts of problems, but its all a trade off.
