The 3913 looks like it was done by Magnaport, not sure about the 4506. I am willing to bet there are more than just those two ported 3rd Gens out there. I believe S&W PC even produced some ported guns, but via extended ported barrels and not slide/barrel combos. While I don't see the need for a ported 9mm or .45 3rd Gen, I would likely prefer a ported version of the say the CS40 or 4040PD. Personal preference only.
I have no issues with ported or compensated guns. The reported negative aspects are mostly false. I have been carrying a G23C for a number of years, having put it through it's paces in a number of day, night, operational, tactical and target shooting venues and have never experienced any of the issue I read about all the time on gun forums.
