Alex, SP 10 mk3 definitely does have a pitch control; it’s built into the outboard power supply.
Fremer’s “hunting” hypothesis is the favorite criticism of DD by those who prefer belt drive, but it is very unfair to apply what is or may be a problem with the SL1200, a low end example of the breed, to all DDs. Otherwise we could bring up the inherent speed irregularities of BD due to belt creep and stylus drag.
Different servo control designs had different correction rates. Apparently the one built into the SL1200 makes very frequent corrections that might be audible to some. Moreover it had a cheap iron core motor.
It’s just my opinion but I would not necessarily agree with your sorting of DDs into 4 categories. And you left out many superb products, but I’m sure you know that. No biggie.
