The right way to compare MC and MM is to buy a turntable with two tonearms and an MM/MC phono stage. If both cartridges carefully selected and matched to the arms then it will be impossible to say which one is better (MM or MC). But most likely MC will cost twice as much that MM. And being cheaper MM has user replaceable stylus (even with exotic cantilever and stylus tip). The situation with MC depends on who will fix the stylus/cantilever when your diamond is worn, after first refurbishing (if it’s not done by manufacturer or original cartridge designer) it can be serious degradation of sound especially for an exotic cartridges when someone will put something else instead of original designers choice. So first retip/refurbishing can ruin the sound of very nice LOMC. It will never happen with MM if the user can change the stylus with the next backup (original) sample.
