In principle I agree with your premise Raul that low and ultra low output mc cartridges generally are finer and more nuanced than medium and high output ones but it's not everything. The character of the cartridge is still most important IMO. When MC2000 came out it was impossible to find a low noise enough tube phono/preamp to use it directly, at least that was case in my system and I recall the sound with the matching SUT was extremely detailed but too analytical for my taste. Never liked the IO either, too colored, too boring and the bass was off. To be honest I never liked anything AN/Kondo. I guess if I had to pick one of the ultra low output cartridges of that time it would be the Denon DL-SL1.
Regarding vdH cartridges I don't hear anything negative in the more recent higher output versions and I've had them all since the Colibri Stradivarius. Up to the end of last year there were some differences between the character of lower output Master Sigs, 0.28-0.34mv and higher output versions 0.75mv-1.1mv but they don't suffer the typical shortcomings of high output mc cartridges, in fact in many newer systems I prefer the higher output version. These days many speakers have low sensitivity and are difficult to drive the higher output is perfect in such systems, you'll get all the dynamics without having to crank up the volume which introduces noise. The Master Sigs I received this year seem to be very close in character irrespective of output.
Of course not always but in clean records pops & clicks can disappear with proper setup.
