I use the rocker rudder because I have a bad habit of twisting my hand around the joystick especially when turning. I dont think you're missing anything, just a matter of preference. In fact I think using the rudder/stick is probably more responsive and your turns may be more coordinated using the stick/rudder combination than the rocker rudder on the throttle.
