Because if you're using a 4WD, your robot bounces all over the place when trying to turn.

The 6WD gives six wheels either contacting or skimming the ground with a shorter wheelbase, which allows for much better turning.

Humm, I see. I did not know that. That is very interesting. We have never attempted a 4 or 6 wheel normal drive, except for lunacy and that doesn't count. We used mechanums fro 2010. I will definitely keep this in mind for the future.
