It depends greatly both on the specific model of the vintage table, and the condition it's in (or can be restored to).
The typical vintage table doesn't stack up well to the really higher end modern stuff (there are exceptions) but will oftentimes stack up well to entry-level-to-mid-level modern stuff.
Anyway... it can vary drastically depending on factors too numerous to mention. I'd recommend not even considering a vintage table unless you're willing to learn about restoration and you consider that sort of stuff to be an adventure rather than a chore. Or unless you're really poor like myself and come across an offer you can't refuse

. Otherwise, I think most people who care about SQ would be better off getting a modern table and avoiding the numerous potential pitfalls of vintage tables.
But it really depends on you! You could end up having a lot of fun, or wishing to god you'd just gone the easier, softer way.
