Why exotic stylus not used on MM?

Let me explain
Of course there are exceptions
The top mm of the Ortofon is a shibata stylus
Nagaoka's Fine Line
Audio-Technica's Fine line
Exotic stylus micro line in third place in AT
(while expected to be in first place)
Micro line, micro ridge, fritz gyger, etc.. They are both absent and they are not at the top as expected

İmho

Old conic an elliptyc

Then Fine line and last shibata

and then exotics are

Micro line, micro ridge, fritz gyger, SAS, ortofon replicant 100, etc.. 

I have a rega rb300 arm on a michell gyrodec. I have analog devices op amps used ss phono stage and pre amplifier. 
I was using Ortofon kontrapunkt b then I put a black
My expectation was that kontrapunkt b would be better
Kontrapunkt b has better bass, tonal balance is in the mid-low than black
Black is vivid, real, airy, tonal balance mid-high than b
Overall, there was a big difference in the sound in favor of black.
My choice was black without hesitation because of it's there feel.
That got me thinking a bit about the overall mm-mc difference
That's why I felt compelled to ask this question.

tobes thank for answer

Ortofon Jubilee (x2), Cadenza Black and A90 - the 2M Black can't compete with those on delicacy, detail, soundstaging etc''

İ thought the same about kontrapunkt b.

' 'You should try the LVB 250 stylus' ' İ agree.
