Agreed.
Anyway I think there is also a different "problem" here. As far I can understand "quality" have different meaning for Americans and Europeans (which in turn have also different flavors depending on the country).
For Americans quality is (more or less) equal to heavier, sturdier, bigger, stronger... and this is not wrong, but quality is also care for the details, evenness on production, evenness of performances during the object life, resilience to accidents and so on.
Looking at the keyboards while a BS, more or less, satisfy both of the visions, other keyboards doesn't.
Most of cherry MX, while likely outlasts most of the RD, are lacking evenness trough the production, thorough the single keys, and during the keyboards life, they are more or less artisianal products with all the minus and all the plus of this this kind of production, they can be killed by a single spill of liquid they can stopped by a single hair inside a microswitch.
Being made by a number of pieces grater than a 7x factor are more prone to failure, because statistics works against them, and so on.
All this is also quality and in that aspects a decent rubberdome wins hands down.
A mech keyboard should be bought because one like it, period. Most of the rational toughs are retrofitted ones, some of them are just lies or misconceptions.
Mechs are things that must be bought with the heart, not with the brain.
