"Been conflicted about whether to acquire - sonics doesn’t measure up to my current audio chain, would I be spending just for looks?"
Thats a hard one to say, was that receiver you listened to restored? ( re-cap etc). Granted even a fully restored unit would sound nice but not up to the audiophile standards of today. There are better vintage choices then most of the 70's early 80's receivers. Event the top integrated and separates from the era are better. Remember all in one receiver was just that all in one so you compromise doing all in one design, like you do today.
So yes, you're buying for nostalgia reasons. Note there are some very good vintage pieces though and some as good as modern gear for musicality, maybe not ultimate detail. I'd say some of the best tuners of the day were better then most made today.
