Extensively swapping back-and-forth between the various mufflers, I have not subjectively felt any performance variations one way or another with any of these three (3) mufflers as the only change.
What did make a huge difference, though, was the deletion of the four (4) cats. The engine now revs quicker, sounds better, runs significantly cooler, and has notably gained gas mileage with this change.
For example, see Post 49 in this thread for more info on our secondary cats:

These cat changes are much more significant for me than any muffler swapping, so I’ve simply settled upon the muffler that I think sounds the best.
Plus, the Dansk sounds "rorty". See 36 minutes into it:
