It depends partly on what you define as vintage... but sticking with the practical division into three categories (idler, belt and DD)...
1. Idler wheel: Probably the Garrard 301 and 401. If you allow for extensive tweaking, you can add the Lenco heavy-platter TTs to that list. Special mention goes to the Thorens TD124, a hybrid belt+idler design.
2. Belt drive: Two groups stand out here: A. Thorens Prestige and Thorens Reference. B. The best (Japanese market only) 1980s ones from Micro Seiki.
3. Direct Drive: Two groups emerge here: A. The Rockport Sirius III, in a class of its own. B. The TOTL/best (Mostly Japanese market only) 1980s ones like the Pioneer Exclusive P3a, the Kenwood L-07D, Yamaha GT-2000X, etc...
Half of the ones mentioned are near-unobtanium for most of us, due to rarity and price. A more useful question might be, what is the best all-around vintage table that I can actually find and afford? For me, so far, that has been the GT-2000, with a few add-ons/upgrades (external power supply, auto arm-lift, original record weight). That doesn't stop me from dreaming, however, about getting a Prestige or Reference, a P3a, or ultimately a Rockport...
