I used to always use PS2 ports when mobos had them because I didn't see the point in wasting a USB port on a keyboard and mouse. Nowadays, you don't often get PS2 ports, and I don't go out of my way to find a mobo with them.
Without a doubt though, I prefer and only use wired keyboards and mice. To me, wireless just seems silly. My cords never get tangled enough to justify changing batteries.
