A few years ago I had the opportunity to compare six M42 and P/K class 200mm primes including Vivitar, Sears, Soligar, Tamron, and Pentax samples. (Also three DA 50-200's.)
One of the things that I found was a subjective feeling that some 200's seem to evolve from the optical formula for the portraiture family (100-150mm) and some appear to be of the long range telephoto family (200-400+). The Super Tak 200/4 was more pleasing at closer range -- say, to 20 ft -- and the Vivitar/Sears(Tokina) 200/3.5 were slightly preferable beyond 50 ft. The SMC-M 200/4 was sort of middle of the road and didn't excel at either end.
Again, this is from samples of one and subjective, but today I would tend to select older 200mm primes (more so than longer or shorter FLs) based on strength in the particular range application. There's also the prejudiced pleasure of just messing about with old Pentax friends to consider too.
This doesn't seem to be as much the case with relatively newer designs I've tried or high-quality primes like my SP 180/2.5.
So I can't say I have one single lens preference from that group other than ranking the Adaptall SP 180/2.5 and SP 80-200/2.8 as the best of my ~200mm choices.
