Seems we are all in agreement. For cars that are driven on a road course (not a drag strip), toe out tends to affect inside tire wear more than negative camber. On a street car, negative camber tends to have more of an affect on inside tire wear than does toe out.
The wear patterns of neg camber wear and toe wear are also quite different. Excessive toe will feather the tread; excessive camber won't. At least on a street car.
