There's a couple of issues:
1) For best groove tracing (and hence lower distortion) a more svelt diamond profile is no doubt going to be superior.
2) For basic cost, price is going to be higher as the grind becomes more contoured. Or at least it should be.
And although distortion is generally lower with a more sophisticated cut, not everything is equal among like designs. For example, in David Rich's analysis of the Sumiko Celebration cartridge he found:
IM between 200 Hz and 2.1 kHz is 2% for the Celebration 40. The value is referenced to the larger 2.1 kHz tone. This is more than twice the best-performing cartridges with a Microridge stylus.
The IM spurs around 17 kHz are referenced to the larger 2.1 kHz tone. The result is 6%. Now we are 3X the best performing cartridges with a Microridge stylus.
At the same time the listener's subjective impression was not particularly negative, and in fact was positive. I have a Denon DL103, which has to be one of the more retro cartridges out there (ball point pen diamond/low compliance), and switching from it to the A/T VM740ML is like raising the shade on the window during a sunny day, in terms of difference. But from a subjective standpoint, with my eyes closed, as it were, the antique Denon design sounds fine, and in some ways (but not others) I like it more.
