I’m not sure of the exact different I assume that HD audio will gives better audio quality but I’ll always go for HD audio if the mainboard has it, if the mainboard only has AC97 then I’ll use AC97 connector. While the connectors may look identical, the pinouts are different and not really interchangeable.

Adding this as a comment in case someone comes across it. An infrared port is included, two serial ports, a parallel port, and four USB ports. On some motherboards it may be possible to disable the plug-in detection so they can work better though still not perfectly with an Cohtroller front panel.
