Obviously there is no "Best" drive train. There is only best for you.

We went with what we dubbed the "Chicken Drive". It is a 6wd tank drive with super shifters. What made it distinctive was redundant chains. We actually busted a drive chain in Newton qualifiers but kept running. Using pneumatic shifters was also very useful. We saw people at regionals trying to shift with servos and that meant they had to basically come to a full stop to do so.
