To clarify, the 8060A true RMS AC is rated up to 100kHz, and the frequency counter up to 200kHz. Still largely unmatched by more than a handful of DMMs, 35 years later.

Yes well things have moved on some to the point where the Chinese can a decent bench DMM with 2.2 million counts, TRMS to 300 KHz and internal counter to 1MHz.

Certainly so, but the 8060A is a handheld.
Also, "don't be too proud of the technological terror they constructed. The ability to tout these numbers is insignificant next to the power of time" (Darth Vader)
Not saying one way or another regarding the Chinese, but the true test of time will take... Well, time.
Designing a product is one thing. Designing a product that is robust is entirely different.

Out of all the classic vintage Fluke meters, which ones are more / most reliable, accurate and easy to repair?
I have a Fluke 25 from 1980s, it is still being used daily.
I just bought a Fluke 8000A in very poor cosmetic condition and with unknown working condition.
Will have to be tested, and repaired if needed.

for hand-helds I'm a huge fan of the 8060a (the manual is fabulous as is the additional info available thanks to Dave T!), and I also like the 80 series (particularly the 87 - but the 87-1 and 87-2/cat3 versions are easier to fix than the 87-3)
It's a toss-up which one I grab off the bench but I probably grab the 87 more just because I don't mind if I break it.
oh, and both have the same dc volts accuracy of 0.05% (except the +counts are 1 and 2 for the 87/8060)

It's really a crap shoot. Depends on how much use/abuse they received. I have an 8000A, two 8800A's, 8600A, 8010A, and 8050A. At the very least you should expect to re-cap the power supply. And then perform a calibration.
The 8000A is a decent 3.5 digit DMM but at least mine suffered from some drift issues. For some reason Fluke decided that the +5V supply didn't need to be regulated. I fixed that by re-designing the power supply. If you want the details of what I did let me know.
