Mike,
You ask a couple of interesting questions, but you need to focus a bit more.

To take Hallicrafters as an example, they made a wide range of
receivers, ranging from the entry level S-38 (really mediocre as you
would expect), to their final, top-of -the line SX-115, still able to
hold its own with modern receivers. (I am ignoring all their pre-WWII
radios).

This would hold true for most manufacturers except for Collins -- where
everything they made was "top of the line". ;-)

I am curious about the longevity of the tube radios on the market.

Again, you should clarify a bit. Not sure what you actually mean by
"longevity".

The components in the tube radios are anywhere from 30 to 70 or more
years old. Once components that age have been replaced, the old set's
service life should generally compare favorably with the solid state radios.
