I don't think it's that simple Stickman.
Given the other system components, most notably the phono preamp, are capable of resolving the "better" cartridge, I believe it's safe to say that any of the 3 would provide a noticeable level of improvement to my ears. OTOH I can think of other cartridges (all more expensive than the 20X) that wouldn't float MY boat.
Again and I don't want to beat this to death but cartridges, like speakers and cables, are very listener dependent.
One man's ceiling is another man's floor as the song goes.
