I know this thread asks what are the best vintage turntables. I can't answer what is the best though, as it is very much based on experience and exposure.
I will say what have been some of my favourite turntables that I have tried. First, a bit of context.
I sell systems and gear I find and have cleaned up or refurbished as a hobby, and to help pay for the gear I am keeping. I have been doing this for a few years now. I have had many turntables, probably over a hundred different kinds, usually in the low end to mid range categories. Some turntables stand out heads and tails over the others.
I am defining vintage gear for the purposes of my response as 70s and 80s gear. Why? Because that is what I've had the most exposure to. Any omissions are only because I haven't encountered them to assess. The criteria that are important to me are; looks, sound quality, feel of controls and tonearm, quality of construction, and weight. Some tables won't show up on my list because I just didn't like using them. The B&O RX is one of those. It has beauty, weight, and sound quality, but I never liked the tonearm controls or feel.
My favourite turntables are;
Philips GA 312 Electronic Turntable. Servo controlled belt drive turntable with AR XA style suspension (spring loaded table and tonearm, touch controls, and a very nice Thorens TD-160 like styling. I have had three of these tables and always liked them a lot, especially with an ADC XLM cartridge.
Sansui SR-222 belt drive. I've had two of these, and there is something about how they look and sound that attracts me to them.
Kenwood KD-2055 Belt Drive table with a synthetic marble base. This table is heavy, solid, well isolated from vibration, and sounds very good. I have also had two of these. For the right price, I would buy one again, even with the funky auto return that inconsistently worked on both of them.
Sony. Just about any Sony turntable sounded better than you would expect, especially their low end turntables. They are surprising. But their better quality turntables really stand out. I have had between 5 and 10 different Sony turntables, all direct drive.
Yamaha PX-3 Linear tracking turntable. I love this table. It is my favourite table of all I have had, and is the primary table I still use in my reference system. It sits beside a Thorens TD-160.
My Thorens TD-160 is my second favourite table. It is more sensitive to vibration, but it sounds the same as the PX-3 even with a different cartridge. I got lucky matching them, and I use these two tables (TD-160 and PX-3) side by side to decide which records are the best in my duplicates.
Denon. I have liked every Denon turntable I have had the pleasure of looking at. They are also really well respected amongst those who know. I have only had one Denon turntable myself(DP-30L), but I have lusted over just about every Denon turntable I have seen. I love the styling, and the build quality of these tables. It was replaced by my Thorens TD-160.
Marantz 6200 belt drive turntable. This was my second turntable after the Denon DP-30L I started with when I got back into turntables. I liked it a lot, but it got beat out in SQ by my B&O RX.
Hitachi PS-48 direct drive. I loved this turntable. Styling, startup power, the ergonomics, controls, and SQ. It was pre-empted by my Yamaha PX-3.
Any Technics Linear Tracking turntable. Technics got these right. Even the cheap ones sound pretty good, but the good ones sound very good indeed. I sold mine because it had some cosmetic issues, but my SL-10 was an excellent performer.
Technics Direct Drive Turntables. These are solid to great performers, depending on the model. I don't care that much for the styling of most, except for the very best. Rugged Industrial look.
Garrard DD75 Direct Drive. This was Garrards first direct drive, and although the motor doesn't have the oomph of other direct drive turntables, it was a pleasure to use and listen to.
AR-XA. Last, but not least, I loved the musicality of my AR-XA. It was a solid performing turntable that just sounded great! A bit sensitive to vibrations, but I never got mine morinified.
As mentioned, these are my favourite tables. This is by no means a definitive list, just a list of what I liked of the tables I have had or tried.
