I can’t tell the difference between the different varieties. Between the “Ultimate 2 Bluetooth Controller” and the “Ultimate 2 Wireless Controller,”

The wireless controller uses a wireless USB dongle for connectivity, which supposedly has way less input delay than standard bluetooth. I couldn’t comment on that personally tho cause I have an older one which is Bluetooth and works fine for me
