Hello there,
In your personal opinion, and especially if you have heard both, which do you prefer? 
Do you feel if Harbeth is overpriced in comparison to the Buchardt? Or if the Harbeth is the better sounding speaker. Do you find that Buchardt speakers tend to be superior sounding to the Harbeth or do you feel it’s the other way around? I think at this point in time, these are the two ultimate speakers to put in comparison with.
