Press Fit vs. Full Floating Wrist Pins
I think that it's more of a manufacturing issue than a "performance" issue.
With press fit rods, you have to control the temperature or you can overheat the rod and make it weaker.
If you use floating pins, you have to worry about a missing/loose clip.
It's not an issue when you are hand building single engines at a time, but when you have to put hundreds, and thousands together, it can become a challenge....
