No performance gains will ever be got between leathers. Your leather would have to be abrasive for that to happen.
The linen counterpart on the other hand can affect the razor. Even more so with compounds. So get the best quality linen, and a good quality leather.
Anything claiming to be a better stropping material for your final leather is hyperbole and the gains will be ephemeral. You are by large grading the audible and tactile feedback and converting that into illusional gains.
