After a few days of watching TBA and reading some of these posts, I'll make perhaps the only valid & incontravertible sweeping generalisation for FRC:

The best drive train is the one that works every match.

This includes all of the subsystems such as electrical wiring, pneumatics (if you shift or have linkages), voltage of the battery at the start of the match, and the control system the drivers use. These concepts should be drilled into rookie teams just as much as any other drive train concept. They are just as important since (well, without voodoo magic) the robot can't move without them.
