My suspicion is that there is zero difference in mechanical accuracy between these two models. The real source of accuracy in these pistols is Volquartsen's excellent trigger and sear, which both models have. I have a Volquartsen fire control group in a Ruger Mark III, and it transforms a very good pistol into an amazing one.
If you have a chance to handle both pistols, go with the one that feels better in your hand. That will be the one you shoot better.
