Mileage definitely varies for BT. I've personally never had any latency issues with BT with ps4 or now xbox elite controllers

This is across my old PC which had an asus wifi ax200 pcie adapter, my laptop which has ax201, and my current PC which has a built in ax200 on the mobo

It was really good for me until one day when I was playing mw and the controller just disconnected completely and did not want to reconnect at all. Ended up buying the dongle and never had any issues at all
