USB or PS2 for mouse?

[TicTac]

I have a MX700 Wireless Optical Mouse and it has a USB>PS2 adapter. I am just wondering if it makes any difference which slot I plug the cable into? (USB or PS2)

Which is better?

Thanks

USB because the wireless communicates at ~130Hz which is perfect for the default 125Hz USB polling.

Even with wired mice, USB is superior due to the ability to hike up the sampling rate up to 1KHz (few mice function at a stable 1KHz, but there is practically no difference from 500Hz and it takes more CPU cycles so I prefer 500Hz).

USB if possible over PS2 when applicable.
