I hope you understand the limitations of your questions. You are talking
about OLD equipment. Chances are that anything you buy made needs some
amount of restoration to make it work as it originally did when new. Most
of the comments in the last week or two are related to comparison of the
products when they were new. They are no longer new.

An old Hallicrafters S-85 (definitely not a high-end receiver) might out
perform an HQ-180 (definitely high end) if the S-85 has been carefully
restored and the HQ-180 needs help.

If you are looking at ebay and the seller says a receiver "works" then you
do not have a clue about how well it works. It might be able to receive the
AM station next door, but hear nothing else. It still "works".
