I don't see the two comparisons as equivalent at all. If two things
are different, it does not follow that they can be ranked. If we have
two objects, such as a spark plug and a cam shaft, it is one thing to
say that the two are not the same object; it is quite another to say
that one is 'greater than' or 'less than' the other.
