If I understand you correctly, then this is all about sympifying 'b' before
doing the
comparison, right?

I'm not sure that I understand you :-) In the comparison method, I would

Can you give an example of an expression that is easier to test with this?
I am not sure about this, though it
does seem like Maple does it:
