AirTight PC-1 supreme vs Dyn XV-1S

I suspect that it is a matter of "flavor". 

What Stringreen said. Plus, it is a matter of your choice of tonearm to go with one cartridge vs the other.  The TT is going to do the same job (maintain constant speed, eliminate resonances, both to the degrees that its design permits) regardless of the cartridge.

My error for not being clearer - apologies.  What I'm asking is, for those who have experience with the Kronos Sparta + Kronoscope RS arm, have you had an opportunity to compare/contrast the XV-1s with AirTight PC-1 Supreme?  I ask, as I understand these two carts to be/have been fairly popular mates with the Kronos tables over the yrs.  

That's got to be a small sample of a very small sample on this forum.  (I am not aware of any regulars who own a Kronos of any kind, and if they are lurking out there, then a very small percentage of them will have auditioned both of those particular cartridges.)  Sometimes you've just got to bite the bullet and do your own evaluation.
