We went to java in 2012 and started with the RobotBuilder tool. It generated a code skeleton derived from IterativeRobot. The IterativeRobot class is contained in sunspotfrcsdk\lib\wpilibj.src\edu\wpi\first\wpilib j. I have not been able to find a CommandBased class in the wpilib.
The IterativeRobot is "command based" in the sense that on every iteration of the control loop, it executes any active commands. I'm not sure how a CommandBased robot would be any different.
As for multi-threading, we can get into a theoretical discussion on the merits of multi-threading on a single CPU platform. In general, I prefer the explicit control of keeping things single threaded and using the setInterruptible or cancel methods if I need to preempt a running command.
But this would be a discussion for a separate thread (so to speak).

The Command Based structure uses the IterativeRobot base class with extra functionality built around it. It sounds like you have been using the Command Based structure.
