Can anybody tell me which turntable is likely to be better in terms of sound quality? (assuming both are in good condition.)
Thank you!

I had a new Denon 47 years ago and a friend still has it - it still works fine. The only problem I noticed early on was the tonearm electronic damping control.
When set to the factory rec it was a bit too much. 1/2 to 1/4 was much better.
The table is nowhere near ultimate but the auto function always worked perfect and it sounded real nice.
I think both would serve very well but the only problem would be life expectancy. Those IC's are no longer made so if something goes wrong you're SOOL.

Thank you for your reply.Whoops... I'm going to change my answer. Let's say, MK II. THAT is my final answer.

The MKI i servo controlled. The MKII is quartz locked, preferable to servo control.
Physically, the MKII has the controls outside the dust cover. on the MKI they are under the cover. Here is a pic of the MKII

It's probable that both versions use a servo mechanism to maintain constant platter speed, but in one of the two versions the action of the servo is governed by the constant frequency oscillation of a quartz crystal as reference. Quartz reference came along I think in the mid to late 70s. Technics tables with quartz referencing about 1979.
Yeah, the difference between the original and MkII (quartz locked) Technics decks is something like .005% in terms of speed stability.I seriously doubt I could tell the difference.

The meaning of the seemingly trivial .005% depends upon how you define "speed stability", assuming your data are correct. (Where did you find that?). It seems to me that .005%, in terms of any concept of speed stability, would be very difficult to measure, and almost certainly it would not be audible. On the other hand, I have never compared a pre-servo Technics TT to a servo-controlled version of the same TT.
I could imagine that the quartz referencing improves upon the regularity and accuracy with which speed corrections are made. So, two versions of the same table with vs without servo might differ in some audible way even though they wouldn't measure much differently in terms of some concepts of speed stability (for example, speed over short time intervals vs longer time intervals).

In this context, speed stability is Wow and Flutter
Well, I guess we can all agree that .005% or 5 parts in 100,000 in wow and flutter is likely to be inaudible, so if the two turntables sound different, it's for another reason, but it could still be a reason related to speed control.
That's just part of the difference. And, you're right, the improved speed stability is probably insignificant. I owned the original SL-120, which is simply the original SL-1200 without a tonearm. I mounted the SME 3009 Series II improved tonearm on my SL-120 and it was definitely a very nice turntable. However, it doesn't compare to my SL-1200 Mk2 from the standpoint of sound quality.The greatest improvement on the SL-1200 Mk2 is a result of damping the plinth. The original version didn't produce bass with the tightness and clarity of the improved SL-1200 Mk2. I thought my SL-120 with SME 3009 sounded good until I heard a better turntable, my Thorens TD-126 Mk III with SME III tonearm. The Thorens reproduced bass with the authority and clarity that was missing in the SL-120 with SME 3009. The newer SL-1200 Mk2 has that same authority and clarity in the bass as my Thorens TD-126 Mk III. Therefore, I think the SL-1200 Mk2 might represent the most noticeable improvement of the entire SL-1200 line except for possibly the newest ones being manufactured today.

You can find information on both of these turntables at the Vinyl Engine website.

Below is a link to specs on vintage Technics decks. Note: The MKII is preferred over the original model.
