I do not have a lot of samples to compare, but the measurements that I collected from the Shure V15VxMR and ShureVx/JICO SAS showed quite some differences:
lower noise and distortion of JICO SAS
much better channel separation and channel balance of the JICO SAS
My take of the reason to these changes is the precision of the stylus shape and alignment in the cantilever. The original was not bad, but there was visible asymmetry of the stylus tip and a somewhat imperfect alignment of the stylus in the cantilever. Probably the quality of polish differed between them as well. With the JICO, I could see a perfect geometry and alignment. Perhaps I was lucky with the sample, but for this case, the SAS was evidently much better than the original.
Frequency response was a bit different with higher level in the 8-20 kHz region of the JICO-SAS, which in the case of the V15Vx was not a bad thing. It makes it possible use a different load to get at perfect flat response.

And that is the question which demands to be properly answered. The pursuit of which is all revealing and busts many myths along the journey.
