I would only use distance from an encoder in autonomous, when you need to travel to a specific point as part of your routine.

Would you mind explaining why one way is better than the other? As one side starts to travel further than the other side the PID loop speeds the corrected side of the drive train up. It's the same effect using a different measurement. We're measuring the difference in speed in the distances traveled compared to the actual speed value.
